Abstract

The novel hetero-stilbene derivatives were synthesized by the Wittig reaction between 2-formyl-4-pyrones and polysubstituted imidazole-based phosphonium salts in the presence of a base. The optical properties of the products were investigated via UV–Vis absorption and fluorescent emission spectroscopy in dilute ethanol solution. Electrochemical properties were also studied by the cyclic voltammetry in CH₂Cl₂ solutions. The phosphorus ylides obtained from α-halocarbonyls were also condensed with 2-formyl-4-pyrone to give two electrochemically inactive and non-emitting products.

4-吡咯酮共轭衍生物的合成、光学性质和电化学行为

摘要以2-甲酰基-4-吡喃酮和多取代咪唑基磷盐为原料，在碱的存在下，采用Wittig反应合成了新型杂二苯乙烯衍生物。用紫外可见吸收光谱和荧光发射光谱研究了产物在稀乙醇溶液中的光学性质。用循环伏安法研究了其在CH2Cl2溶液中的电化学性能。α-卤代羰基得到的磷酰基也与2-甲酰基-4-吡咯酮缩合，得到两种电化学活性不强且不发光的产物。关键词:循环伏安法wittig反应(E)-stilbenes荧光发射多取代咪唑唑-吡咯酮致谢作者感谢大不里士大学研究工作的资助。披露声明作者未报告潜在的利益冲突。
