摘要
本文合成了3个新型中位分别为N,N-二甲基苯胺、对-甲氧基苯基或苯基取代的含稠合外环的硼-二吡咯亚甲基染料。研究了它们的吸收光谱、稳态荧光光谱和电化学性质;采用荧光光谱滴定方法研究了它们在强极性溶剂中对氢离子的响应;将氢离子滴加到N,N-二甲基苯胺取代的硼-二吡咯亚甲基染料(1)的CH3CN-H2O(1∶1,V/V)溶液中,其溶液的荧光显著增强;染料1在可见光激发下,可以作为酸性pH范围内检测氢离子的荧光探针。
Three new exocyclic ring-fused boron-dipyrromethene(BDP)dyes with N,N-dimethylaniline,p-methoxyphenyl or phenyl subunit at meso-position were synthesized.Their absorption,steady-state fluorescence and electrochemical properties were investigated.The spectrofluorometric titrations were performed to examine their responsive abilities to H^+ in strong polar solvent.The dimethylanilino-substituted BDP dye 1 showed a large fluorescence enhancement upon adding H^+ to its CH3CN-H2O(1∶1,V/V)solution.BDP 1 can be used as a fluorescent probe for H^+ in the acidic pH range excited with visible light.
