卟啉降冰片烯聚合物的合成、表征及性质研究

摘要

Porphyrinic and long-chain alkyl norbornene monomers have been designed and synthesized, and copolymers were obtained via ROMP (ring-opening metathesis polymerization) using a Grubbs initiator. The properties of porphyrinic polynorbornenes have been investigated by UV-Vis absorption spectroscopy, steady-state fluorescence spectroscopy, lifetime measurements and electrochemistry. The copolymers exhibit almost identical characteristics as well as porphyrinic monomers in photophysics and electrochemistry.%本文设计合成了卟啉的降冰片烯单体,采用Grubbs催化剂与长链烷基的降冰片烯单体开环易位聚合,直接得到了卟啉降冰片烯聚合物,通过紫外-可见吸收光谱、荧光光谱、电化学等手段研究了卟啉降冰片烯聚合物的性质,与小分子单体相比,所得卟啉高分子共聚物相当好地保持了卟啉应有的光物理、电化学等特性.
