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。
In this paper, the synthesis, spectroscopic and electrochemical properties of two fused-ring-containing boron-dipyrromethene dyes substituted with two kinds of benzo crown ether subunits were reported. The results show that the incorporation of electron-withdrawing ester groups into the fluorophore makes compound 2 a highly sensitive fluorescent probe for the detection of sodium ions.
