检测钠离子的荧光探针:含稠合外环的硼-二吡咯亚甲基染料的合成与光物理性质研究

摘要

Two new exocyclic ring-fused boron-dipyrromethene (BDP) dyes with benzo crown ether subunit at meso-position were prepared. Their spectroscopic and electrochemical properties were investigated. The introduction of the electron withdrawing ester groups to the chromophore makes compound 2 to be a very sensitive fluorescent probe for Na+ analysis.%本文报道了两种中位为苯并冠醚亚单元取代的含稠合外环的硼-二吡咯亚甲基染料的合成、光谱和电化学性质.研究结果表明:在荧光团中引入吸电子的酯基使化合物2成为一种高灵敏性的检测钠离子的荧光探针.
