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。

Abstract: 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.

Keywords: Boron-dipyrromethene (BDP) dyes fused exocyclic rings H⁺ recognition electron transfer, fluorescent sensor
