Abstract
Three new homochiral metal bromides, namely, ( l -Htp) 2 Cu 2 Br 4 ( 1 ), ( l -Htp)( l -tp)CdBr 3 ( 2 ), and ( l -tp) 2 ZnBr 2 ( 3 ), were prepared using l -thioproline as the chiral template. These compounds feature dimeric, chainlike, and monomeric structures. Their second-harmonic-generation (SHG) efficiencies are 0.1, 0.3, and 2.0 times that of KH 2 PO 4, respectively. Density functional theory calculations were performed to reveal the origin of the SHG response of compound 3 .
