While a number of highly luminescent copper(I) halide based hybrid materials built on coordinate bonds (Cu–L; L = N, P, S-based ligands) have been obtained, the poor structural stability largely limited their commercialization. In contrast, according to the previous studies, the ionic structures (L-free) are more stable than those built on Cu–L coordinate bonds. However, the extremely weak emission hinders their optical applications. Herein, we report a tetra-alkylammonium-cation-induced strategy for the synthesis of stable and highly luminescent ionic CuBr-based hybrid materials. It is interesting to find that the tetra-alkylammonium cations with different chains could induce diverse CuBr-based anions. Moreover, most of these CuBr-based hybrids are highly luminescent, which makes them promising candidates as an alternative to phosphors and with potential applications in sensing.

高发光纯离子溴化铜（I）杂化材料族

虽然已经获得了许多基于配位键（Cu–L； L = N，P，S的配体）的高发光卤化铜杂化材料，但其差的结构稳定性极大地限制了它们的商业化。相反，根据先前的研究，离子结构（无L）比基于Cu–L配位键的离子结构更稳定。然而，极弱的发射阻碍了它们的光学应用。在本文中，我们报告了四烷基铵阳离子诱导的策略，用于合成稳定且高度发光的离子型CuBr基杂化材料。有趣的是发现具有不同链的四烷基铵阳离子可以诱导多种基于CuBr的阴离子。而且，大多数这些基于CuBr的杂化物都具有很高的发光度，
