| The objectives described for the new polyfluorene site are clear and also appropriate for Misplaced Pages. No duplicated information was found during a search of other sites. The topics proposed in the objectives and outline will provide good coverage of the subject and give a much-needed update to the current site.

| The topics listed in the outline seem as though they will provide a discussion that meets the goals stated in the objectives. The sections are organized well and ordered appropriately. The length seems like it will be appropriate for providing a good overview of polyfluorene/s while still being a manageable length for a course project.

| In terms of merging or splitting sections, I would be cautious when writing the section on “Discovery of Polyfluorenes and their Interesting Properties." It seems that a lot of information will be covered in this section, so I advise to keep it well organized to make it clear for the reader. You might even want to consider splitting the section into one about discovery and one about properties for better organization. If you decide to keep it as one section, I suggest re-phrasing the section title, perhaps to something along the lines of "Discovery and Properties" (something doesn't sound quite right with the current phrasing). | |||
| There is one concept which I did want to mention: from what I have seen in the literature, unwanted green emission has been a challenge associated with blue-emitting polyfluorene LEDs. It is unclear from the outline whether this will be discussed in the new site, but I think it is an important challenge to address. I see that your reference by Lin ''et al''. (2010) discusses this unwanted emission. Another article you can refer to is by Romaner ''et al''. in ''Adv. Funct. Mater.'' '''2003''', ''13'', 8 (). The topic of this unwanted green emission would probably work in either "Polyfluorenes as electroactive polymers" or "Industrial Uses of Polyfluorene," depending on the discussion at hand. | |||
| === Images === | |||
| The image included with the outline looks very nice; it is clearly drawn and of a good size. The image also appears to follow the appropriate ChemDraw settings.

Since the image is a supplement to a topic explained in the text, the figure will serve to clarify the discussion by providing an example for the reader. | |||
| The site would definitely benefit from a good selection of images. I think it would be a good idea to include an image of the basic polyfluorene repeat unit like the one featured on the current site. Also, many eye-catching and colorful images could be provided for the discussion on industrial applications. | |||
| === Section 3 === | |||
| You have chosen a great selection of articles to reference, however your reference list is not very diverse. It would be a good idea to include other sources, such as websites and/or books (especially since not everyone has ready access to journal articles). There are a few books which discuss polyfluorenes that are available for full online access via the U of M library website, such as ''Polyfluorenes'' by Ullrich Scherf and Dieter Neher (2008). Also, I noticed that your references are not formatted uniformly. You may want to change this to have the references look more consistent. After a brief literature search, I do not see any key references missing from your list. | |||
| === Overall Comments === | |||
| The objectives and outline for the new site look very promising. The current site desperately needs an upgrade, so I think it is great that you are taking on this project. The topics addressed in the outline will provide a good overview of polyfluorenes. The proposed sections are organized well and cover key concepts. I would definitely link to other sites from this page in order to provide supplementary information for the reader. It would also be a good idea to add some diversity to your references by including websites and books. I think you could have a lot of fun with the images you pick for the site considering your topic. Overall, this is a great start to the project, and I look forward to reading the completed product!

Revision as of 05:05, 18 February 2011
Polyfluorene Peer Review
The current site has basic information, but has some sources that could be useful. It’s explanation of the basic polymer backbone with the monomer units is simple and to the point with a good image to enforce this detail. This site however is not very detailed and I agree that it needs attention and is a worthy subject to work with. Review read: Source 17 on sandbox: J. POLYM. SCI. PART A: POLYM. CHEM 39: 2867-2873
Section 1.
- The objectives are clear and original, since they would expand the current site and add many new ideas, with historical, synthetic and application sections. There does not appear to be any sites with duplicate information. It would be recommended that the site contain links to the Misplaced Pages fluorene site, which will explain some basic properties of the monomer, although this site itself is not very thorough. Other useful related links could be the electroluminescence page, conjugated systems page, quantum efficiency page, and the OLED page. Many others could also be used. The suggested length of the page is definitely feasible for a semester long project and would add more than the requirements for the assignment to the site.
Section 2.
- The length of the work seems to be appropriate. There is not more being added to the site than can be handled by a two -person team. I don’t think that splitting any of the sections would be useful, but some small things could be added, such as how defects/doping affect the properties. How do different R groups on the fluorene change the properties? Be sure to explain briefly what each of the properties mean and link to respective sites if there are any. Since the original site is very limited, any work on the site would compliment the limited original site with its basic fluorene unit and some basic properties. It would definitely build it into a better page, with much more background, synthetic and application information. This section does meet the stated objectives well and should give people a clear understanding of basics of polyfluorene. One thing that could be changed is the “Industrial Uses of Polyfluorene” to just “Applications of Polyfluorene.” Maybe it sounds friendlier. It may be useful to mention stability based on repeated excitation events or cyclic voltametry tests if the data exists. How much does this affect degradation?
Images.
- It is not clear from the structure given on the page, which part of that monomer unit is the actual polyfluorene molecule. So it could be difficult to know what they are looking at without reading through the text. This molecules take home message seems to be that this is an example of some repeat unit, however a brief description of its specific properties may give it a stronger message. It may just be helpful to show the polyfluorene by itself like it is on the original page. The image looks good for the site and is a legible size, with good resolution. From the looks of the image, the appropriate Chemdraw settings were used. More images would definitely be useful, possibly even a picture of the fluorescence occuring or a table of repeat polymer units.
Section 3.
- The references need to be diversified; nearly every reference is a journal article that the majority of the public would not have access. Also add DOI numbers. Here are a few books that may be useful as sources: “Advances in Polymer Science: Polyfluorenes” by Ullrich Scherf 2008, this book gives information about applications in OLED’s, focus on emissive defects, electroluminescence efficiency, band gap tuning, and the incorporation of charge-transfer substituents in the context of hole and electron injection. “Organic light-emitting materials and devices” by Hong Meng pg's 159 and 122, 2007, contains a few short sections also. I also found an interesting short article out of Popular Science that uses polyfluorenes as sensors. (Laser Sensor Can See Explosives' Vapor Trails Even at Extremely Low Concentrations, posted 6/7/10 by: Clay Dillow. Also check C&EN “Better blue for polyfluorene OLED’s”. These would all be good articles with simpler understanding for the average person. Also check out Scientific American and Popular Mechanics to see if additional lay-person articles exist. Your list of resources is very extensive and has many good review articles. I found the original articles out of the 1800’s quite interesting and I believe this is a very excellent way to start the historical background.
Overall.
- I believe that you have the start of what will become a nice site. The sections you decided to mention as well as your objectives seem well within the realm of the scope of the project, and polyfluorenes seem to be relevant compounds in today’s market. My research this semester has sort of been based on these kinds of properties. Your images look very nice, and you have a great number of primary source materials. I like the historical background back the 1880’s. I would recommend adding more alternative sources such as books and magazines to your resource repertoire. This would allow more people to access this information. I would also recommend putting strong emphasis on these compounds have emission over the entire visible range; which is probably one of the most important properties. Be sure to add more images and tables as mentioned above. Good Start!

Peer Review: Polyfluorene
Section 1
The objectives described for the new polyfluorene site are clear and also appropriate for Misplaced Pages. No duplicated information was found during a search of other sites. The topics proposed in the objectives and outline will provide good coverage of the subject and give a much-needed update to the current site. Judging from the objectives and outline, the article will be of a feasible length for both a course project and a Misplaced Pages article. The following is a suggestion of sites that could be linked to from this site: fluorene, luminophore, electroluminescence, photoluminescence, and polymer light-emitting diodes.
Section 2
The topics listed in the outline seem as though they will provide a discussion that meets the goals stated in the objectives. The sections are organized well and ordered appropriately. The length seems like it will be appropriate for providing a good overview of polyfluorene/s while still being a manageable length for a course project. The proposed additions to the site will be complementary to the current site, adding important information which the current site lacks.
In terms of merging or splitting sections, I would be cautious when writing the section on “Discovery of Polyfluorenes and their Interesting Properties." It seems that a lot of information will be covered in this section, so I advise to keep it well organized to make it clear for the reader. You might even want to consider splitting the section into one about discovery and one about properties for better organization. If you decide to keep it as one section, I suggest re-phrasing the section title, perhaps to something along the lines of "Discovery and Properties" (something doesn't sound quite right with the current phrasing).
There is one concept which I did want to mention: from what I have seen in the literature, unwanted green emission has been a challenge associated with blue-emitting polyfluorene LEDs.

(2010) discusses this unwanted emission. Another article you can refer to is by Romaner et al. in Adv. Funct. Mater. 2003, 13, 8 (link to article). The topic of this unwanted green emission would probably work in either "Polyfluorenes as electroactive polymers" or "Industrial Uses of Polyfluorene," depending on the discussion at hand.

The image included with the outline looks very nice; it is clearly drawn and of a good size. The image also appears to follow the appropriate ChemDraw settings. Further, the image makes sense on its own and has a clear caption.
