The synthesis, photochromic features, and electrochemistry of a novel material based on dithienylethene (DTE) and 3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine (didecyl-ProDOT) units are described. It is noteworthy that 1,2-bis(5-(3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yl)-2-methylthiophen-3-yl)cyclopent-1-ene can be efficiently switched between open and closed states by light in both solution and in the solid poly(methyl metacrylate) (PMMA) matrix. It is also found that the emission of this novel compound can be switched on and off upon irradiation.
描述了一种基于二噻吩乙烯(DTE)和3,3-二癸基-3,4-二氢-2H-噻吩[3,4-b][1,4]二氧环戊烯(didecyl-ProDOT)单元的新材料的合成、光致变色特征和电化学性质。值得注意的是,1,2-bis(5-(3,3-二癸基-3,4-二氢-2H-噻吩[3,4-b][1,4]二氧环戊烯-6-基)-2-甲硫代吡啶-3-基)环戊-1-烯可以在溶液和固体聚甲基丙烯酸甲酯(PMMA)基体中,通过光照高效地在开态和闭态之间切换。此外,还发现该新化合物的发射信号可以在照射下被开启和关闭。
