contactWhile 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.
