线性共轭多吡咯及其金属络合物具有优异的光电性质，在有机合成、生物医学、材料科学、超分子化学等领域有重要应用。目前限制该类分子进一步应用的主要因素是缺乏具有良好稳定性和溶解性的大共轭度线性共轭多吡咯分子及其有效合成方法。本课题旨在发展1,1’-位共轭相连的二吡咯甲川多聚物的新型合成方法；设计合成一些具有良好稳定性和溶解性的大共轭度新型线性共轭多吡咯及其金属络合物;研究目标分子的光谱、光化学稳定性、电化学性能、空间结构及手性配体环境中金属-金属、金属-配体、配体-配体间相互作用，初步探索这些目标分子在有机场效应晶体管中的应用。本项目的开展对于调控线性共轭多吡咯结构及其光电性能具有重要的理论意义和应用价值。

Linear conjugated oligopyrroles and their metal complexes have excellent optic and electronic properties, and have found important applications in organic synthesis, bio-medicine, materials science and supramolecular chemistry areas. Currently, their further applications have been hampered by the limited availability of highly conjugated linear oligopyrroles posessing high stability and good solubility and their efficient synthesis. In this project, we will develop efficient synthetic method for 1,1'- conjugated linear oligodipyrromethenes, prepare several highly stable and good- soluble novel large conjugated linear oligopyrroles and their metal complexes, study their structure, the spectroscopic and electrochemical properties, and photo-stability of these target molecules. We will also investigate the interactions between metal-metal, metal-ligand and ligand-ligand within this chiral ligand environment, and perform preliminary investigation of the application of some of these molecules as novel organic thin film transistor. This project will have important theoretical significance and application value for the tune of the structure, optic and electronic properties of linear conjugated oligopyrroles.
