摘要
卟啉/酞菁是一类高度共轭的杂环化合物,如何实现光电性质的精准调控是推动其光电应用的关键.分子电场是分子偶极或者分子晶体中偶极在分子或晶体内部引发的一种局域电场.对分子电场的调变相当于改变了分子或晶体的固有偶极,进而影响材料的载流子传输及光学性质,因此分子电场优化是调控材料光电性能的一种有效方法.本文阐述了分子偶极与分子电场的关系,综述了卟啉/酞菁分子电场调控其光电性能的研究工作,并介绍了本课题组发展的分子电场有效调控电荷传输行为的研究工作,阐明了分子电场对光电材料电荷分离传输及光学性质调变机制,对新型卟啉/酞菁光电材料理性设计提供了全新的研究思路.
Porphyrin/phthalocyanine is a kind of highly conjugated heterocyclic compounds.Effectively controlling their optoelectronic properties is one of key factors to realize the optoelectronic applications.Molecular electric field(MEF)is a local electric field induced by molecular dipole or dipole in molecular crystal in molecule or crystal.Modulation of MEF is to change the intrinsic dipole of molecule or crystal,further influencing the carrier transport and optical properties of materials.Thus,optimization of MEF is an effective method to regulate the optoelectronic properties of materials.In this review,the relationship between molecular dipole and MEF is expounded.The related work about the regulation of porphyrin/phthalocyanine photoelectric properties by the design of MEF is also summarized.And the studies reported by our group about the regulation of optoelectronic properties by MEF are introduced.The modulation law of charge separation and transport and optoelectronic properties of porphyrin/phthalocyanine materials by MEF is clarified.This could give a new insight to design the new porphyrin/phthalocyanine optoelectronic materials.
