Abstract

Abstract : By using chiral diamines a chiral 3D coordination polymer is assembled to show reversible chiroptical switching behavior by UV/microwave irradiation. Abstract : A 3D coordination polymer {[Cd(L 1 )(L 2 )]2 } n (1 ) spontaneously resolves into enantiomorphic crystals of1P and1M without any chiral source. Bulk quantities of1P and1M can be predictably and reliably obtained by using chiral cyclohexane-1, 2-diamine.1 can be transformed into {[Cd(L 1 )(L 3 )0.5 ]2 } n (2 ) by highly selective [2+2] photodimerization ofL 2 ligands. The reverse process can be achieved by microwave irradiation. The cycloreversion/cycloaddition cycles result in chiroptical switching behavior.
