Photochemistry, synthesis, nucleophilic addition photoreaction, low temperature photolysis, and quantum yield calculations of representative members have been studied in understanding the mechanism of the photofragmentation of mesoionic 1,3,4-thiadiazoles. Quantum yield calculations suggest self quenching and unimolecularity in the ring opening reaction while timed interval IR recording shows the formation
为了理解中离子1,3,4-噻二唑的光致碎裂机理,已经研究了代表性成员的光化学,合成,亲核加成光反应,低温光解和量子产率计算。量子产率计算表明开环反应具有自猝灭性和单分子性,而定时间隔红外记录显示光解过程中形成了杂多烯。
