An, Xiang published the artcileUniversal 4-qualifiable fluorene-based building blocks for potential optoelectronic applications, Synthetic Route of 111-83-1, the publication is Chinese Chemical Letters (2022), 33(12), 5137-5141, database is CAplus.
Herein, a universal 4-qualifiable fluorene-based building block I, which is a fundamental mol. segment to functionalize and obtain novel conjugated materials, was demonstrated. Compared to the traditional modification at 9-site, addnl. 4-position functionalization provided an exciting blueprint to not only tune electronic structure and excited state via p-n mol. design engineering and space charge-transfer strategy, but also allow for optimizing intermol. arrangement and obtaining solution-processing ability. The introduction of the 4-site substituent in fluorene based semiconductors may endow materials with unique properties. Finally, two stable deep-blue light-emitting conjugated polymers, PODOPF and PODOF, by utilizing the 4-substituent fluorene based building block were successfully prepared It is believable that the performance, stability and processibility of reported outstanding fluorene-based conjugated mols. can be further optimized based on this universal building block.
