Oligo(2,5-thienyleneethynylene)s (OTE) with terminal donor-acceptor substitution were synthesized by applying Sono-gashira-Hagihara reactions and a protection group technique. The combination of the alkylthio and nitro substituents provides a DAOTE series, whose long-wavelength absorption shows a monotonous bathochromic effect for increasing numbers n of repeat units. The convergence limit is already
应用 Sono-gashira-Hagihara 反应和保护基技术合成了具有末端供体-受体取代的 Oligo(2,5-thienyleneethynylene)s (OTE)。烷硫基和硝基取代基的组合提供了 DAOTE 系列,其长波长吸收对于增加 n 的重复单元数显示出单调的红变色效应。n = 3 时已经达到收敛极限。
