and enantiopure (D,R,D)/(L,S,L) binuclear PtII complexes with metal-induced planar chirality were designed and prepared by using soft-bridged achiral and chiral ligands, respectively. Their phosphorescence quantum yields up to 100 % can be achieved by shortening intramolecular Pt−Pt distance for highly efficient solution-processed circularly polarized OLEDs.
采用软桥非手性和手性配体分别设计和制备了具有金属诱导平面手性的外消旋 ( R )/( S ) 和对映体纯 ( D , R , D )/( L , S , L ) 双核 Pt II配合物. 通过缩短高效溶液处理圆偏振 OLED 的分子内 Pt-Pt 距离,可以实现高达 100% 的磷光量子产率。
