摘　　要：通过对2个N,N-二吡啶胺基受体修饰的自由卟啉化合物(Porphyrin-2-DPA)光学识别性能的系统研究,可以得知:该卟啉化合物中心刚性共轭的四吡咯环状结构不仅作为灵敏的光学信号基团、更是作为第一离子配位受体,在非共轭的N,N-二吡啶胺基受体辅助下,对Pb2+/Cu2+离子表现出灵敏的多重信号分析识别功能。The optical properties of a metal-free tetra(aryl)porphyrin with two N,N-di(2-pyridylmethyl)amino groups (Porphyrin-2-DPA) upon respective addition of different metal ion were investigated. Systemic studies show that the rigid π-conjugated tetrapyrrole macrocyclic moiety of Porphyrin-2-DPA is employed not only as the sensitive signaling fluorophore but also as the primary receptor with excellent binding affinity and distinctive selectivity to metal ion, which together with the no-conjugated DPA auxiliary receptor endows Porphyrin-2-DPA the sensitive versatile sensor to Pb2+/Cu2+ on the basis of dual-optical signals.
