In 2022,Ohshita, Joji; Ohta, Akiyoshi; Saadom, Siti Zulaikha Binti; Adachi, Yohei; Murakami, Hideki; Haino, Takeharu published an article in Polymer Journal (Tokyo, Japan). The title of the article was 《Synthesis and optical properties of disiloxane-linked decathiophene and dodecathiophene polymers》.Name: 2,5-Dibromothiophene The author mentioned the following in the article:
Disiloxane-linked decathiophene and dodecathiophene polymers were prepared and their optical properties were examined Compared with the monosilane-linked congeners reported previously, these polymers showed slightly red shifted absorption and PL bands in solution Interestingly, the PL bands were red shifted when the spectra were measured in film, and the red shifts became pronounced as the silicon linkers were elongated from monosilane to disiloxane. This is likely due to the enhanced aggregation of the oligothiophene units, reflecting the improved flexibility of the silicon linkers. After reading the article, we found that the author used 2,5-Dibromothiophene(cas: 3141-27-3Name: 2,5-Dibromothiophene)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used in the preparation of soluble α,ω-diformyl-a-oligothiophenes.Name: 2,5-Dibromothiophene
