syntheses of 4′-substituted chiral 2,2′:6′,2″-terpyridine (tpy) ligands with predetermined configurations and directionalities are rather limited in the supramolecular chemistry field. In this study, a carbazole-linked ditopic chiral ligand L was synthesized using 4′-bromo-substituted pineno-fused tpy 5 as the precursor. Upon complexation with Cd(NO3)2·4H2O and Zn(NO3)2·6H2O, two enantiomerically pure
具有预定构型和方向性的4'-取代的手性2,2':6',2''-吡啶(tpy)配体的合成在超分子化学领域中相当有限。在这项研究中,咔唑连接的对位手性配体L合成了4'-溴取代的pineno融合的tpy 5作为前体。在与Cd(NO 3)2 ·4H 2 O和Zn(NO 3)2 ·6H 2 O络合后,两种对映体纯的金属超超分子[Cd 3 L 3 ]和[Zn 4 L 4已通过NMR,电喷雾电离质谱,行波离子迁移率质谱和DOSY分析进行了自组装和表征。此外,它们的光学特性还具有紫外可见,荧光,圆二色性和圆偏振发光特性,这表明可以通过自组装从配体到金属中心进行有效的传输和手性放大。
