摘　　要：Two pairs of Pt(Ⅱ) enantiomers((RR)/(SS)-Py Pt,((RR)/(SS)-Py: N,N’-(1,2-diphenylethane-1,2-diyl)dipicolinamide;(RR)-P/M-QPt,((RR)/(SS)-Q: N,N’-((1R,2R)-1,2-diphenylethane-1,2-diyl)bis(quinoline-2-carboxamide)) were synthesized, respectively, with good circularly polarized luminescence(CPL) and tunable dissymmetry factors(g) by molecular self-induction with(RR)/(SS)-1,2-diphenylethane-1,2-diamine as carbon chiral sources. In the(RR)-P-QPt and(SS)-M-QPt, specific P-and M-configurations were effectively induced from intrinsic chiral carbon centres(R or S), ingeniously avoiding the racemic mixture formation and chiral separation. Furthermore, the chirality originating from both chiral carbon centres and helicene-like structure improves the g factor significantly, which provides a new molecular design strategy for chiral Pt(II) enantiomers with good CPL properties.
