Abstract The intramolecular photochemical processes excimer formation and charge-transfer (CT) complex formation were investigated by comparing the behavior of α,ω-di(1-naphthyl)permethyloligosilanes ((1-naphthyl)-(SiMe2) n -(1-naphthyl); NS n N , n = 1, 3, and 6) and 1-(1-naphthyl)permethyloligosilanes ((1-naphthyl)-(SiMe2) n -Me; NS n , n = 1, 3, and 6) by use of stationary and time-resolved fluorescence
摘要 通过比较α,ω-二(1-萘基)过甲基低聚硅烷((1-萘基)-(SiMe 2) n- (1- )的行为,研究了分子内光化学过程受激准分子的形成和电荷转移(CT)络合物的形成。萘基); NS n N , n = 1、3和6)和1-(1-萘基)过甲基低聚硅烷((1-萘基)-(SiMe 2) n -Me; NS n , n = 1,3和6 6)通过使用固定和时间分辨荧光(TR-FL)测量。准分子和CT复合物的形成高度依赖于硅链的长度和介质的极性。 图形摘要 分子内受激准分子的萘基和硅烷部分之间在两个萘基和电荷转移的相互作用之间形成了通过使用时间相关单光子计数方法的研究。
