quasi-1D structures of (ZnCl2)n and (ZnI2)n chains. The two AEC ligands in one hybrid molecule are dissymmetric due to the steric hindrance effect of the AEC moiety and the hydrogen bonding of the CH3CN guest molecules. The UV/Vis spectra of compounds 1–4 were measured, and the optical energy gaps (Eg) of compounds 1–3 are very close to that of AEC; the value of Eg for compound 4 is a little smaller. Steady

配体是不对称的。测量了化合物1-4的UV/Vis光谱,化合物1-3的光能隙(Eg)与AEC非常接近;化合物 4 的 Eg 值要小一些。稳定和瞬态光致发光研究表明,化合物 1-3 的发射归因于 AEC
