Alkylthio(SR)-functionalized polymers poly(3-alkylthio-2,5-thiophenediyl-1,4-phenylene-alt-4-alkylthio-2,5-thiophenediyl-1,4-phenylene) (P1, alkyl = butyl, octyl and dodecyl) and poly[4,4′-bis(alkylthio)-2,2′-bithiophene-5,5′-diyl-alt-1,4-phenylene] (P2, alkyl = butyl, octyl and dodecyl) have been synthesized by Grignard coupling and FeCl3 oxidation methods, respectively. Spectral measurements indicate
烷硫基(SR)-官能化聚合物聚(3-烷硫基-2,5-噻吩二基-1,4-亚苯基-alt-4-烷硫基-2,5-噻吩二基-1,4-亚苯基)(P1,烷基=丁基,辛基和十二烷基)和聚[4,4'-双(烷硫基)-2,2'-联噻吩-5,5'-二基-alt-1,4-亚苯基](P2,烷基 = 丁基、辛基和十二烷基)分别采用格氏偶联法和 FeCl3 氧化法合成。光谱测量表明它们具有很强的荧光性,量子产率可与它们的烷基(R)-功能化类似物聚(3-烷基-2,5-噻吩二基-1,4-亚苯基-alt-4-烷基-2 ,5-噻吩二基-1,4-亚苯基)(P1',烷基 = 丁基、辛基和十二烷基)和聚(4,4'-二烷基-2,2'-二噻吩-5,5'-二基-alt-1 ,4-亚苯基)(P2',烷基 = 丁基、辛基和十二烷基)。P1 和 P2 的热稳定性不如 P1' 和 P2',因为是烷硫基而不是烷基。调制差示扫描量热法 (MDSC) 研究揭示了长侧链对玻璃化转变的增塑作用
