一种新型中性一价铜配合物的合成、晶体结构与光物理性能
Synthesis, Structure and Photophysical Properties of a New Neutral Copper(Ⅰ) Complex
摘要
Abstract
A new neutral heteroleptic copper(Ⅰ) complex supported by diimine and diphosphine ligands was successfully synthesized and characterized by 1 HNMR,13CNMR,31PNMR and single-crystal X-ray diffraction.This complex adopts a typical distorted tetrahedral configuration and shows high stability in solid state.Theory calculation results show the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of the complex have little metal character,and the lowest energy electronic transition is mainly ligand-to-ligand charge transfer (LLCT) transition.This complex shows intense emission with relative high efficiency and long lifetime in solid state,and analysis of the photophysical data recorded at 298 K and 77 K indicates the emission is phosphorescence stemming from triplet state.关键词
