Abstract

Organic–inorganic copper(I) halide complexes have attracted attention due to their optoelectronic properties and non-toxic nature. In this study, we systematically synthesized copper(I) halide melamine complexes as single crystals, (CuBr(melamine) and CuI(melamine)) and polycrystalline powders, CuBr_xI_1-x(melamine) (0 ≤ x ≤ 1). The crystal structures of CuBr(melamine) and CuI(melamine) are isotypic with a triclinic space group P $\bar{1}$ , where copper(I) is connected with three adjacent halides along the a-axis and a single melamine ligand along the c-axis, forming an infinite stair-chain structure. The photoluminescence emission peaks of CuBr_xI_1-x(melamine) (0 ≤ x ≤ 1) show a red shift from 455 nm to 520 nm with the substitution of Br for I. This finding explains the structure–property relationship of organic–inorganic copper(I) halide complexes and provides guidelines for developing new organic–inorganic optoelectronic materials.

CuBrxI1−x（三聚氰胺）（0≤x≤1）配合物的晶体结构和光致发光性能

有机-无机卤化铜配合物因其光电特性和无毒特性而受到广泛关注。本研究系统合成了卤化铜(I)三聚氰胺配合物单晶（cur（三聚氰胺）和CuI（三聚氰胺））和多晶粉末CuBrxI1-x（三聚氰胺）（0≤x≤1）。cur（三聚氰胺）和CuI（三聚氰胺）的晶体结构是等型的，具有三斜空间群p1¯，其中铜(I)沿a轴与相邻的三个卤化物相连，沿c轴与单个三聚氰胺配体相连，形成无限阶梯链结构。CuBrxI1-x（三聚氰胺）（0≤x≤1）的光致发光峰在Br取代I后从455nm红移至520nm。这一发现解释了有机-无机卤化铜配合物的结构-性能关系，为开发新型有机-无机光电材料提供了指导。
