Two kinds of chiral 1,1-binaphthol (BINOL)-based polymer enantiomers were designed and synthesized by the polymerization of 5,5-((2,2-bis (octyloxy)-[1,1-binaphthalene]-3,3-diyl)bis(ethyne-2,1-diyl))bis(2-hydroxybenzaldehyde) (M1) with alkyl diamine (M2) via nucleophilic addition-elimination reaction. The resulting chiral polymers can exhibit mirror image cotton effects either in the absence or in the presence of Zn2+ ion. Almost no fluorescence or circularly polarized luminescence (CPL) emission could be observed for two chiral BINOL-based polymer enantiomers in the absence of Zn2+. Interestingly, the chiral polymers can show strong fluorescence and CPL response signals upon the addition of Zn2+, which can be attributed to Zn2+-coordination fluorescence enhancement effect. This work can develop a new strategy on the design of the novel CPL materials via metal-coordination reaction. (c) 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 1282-1288
