Selective formation of luminescent chiral cocrystal: Molecular self-assembly of 2,2′-binaphthol and 2-(3-pyridyl)-1H-benzimidazole

Luminescent chiral cocrystal based on the self-assembly of 2,2'-binaphthol and 2-(3-pyridyl)-1H-benzimidazole (P.) has been developed, in which 100% R configuration of BINOL can be obtained in the cocrystal products. The final structure presents the same P.R. The studies suggested that the co-crystallization approach could have much flexibility and potential applications for the design of chiral fluorescent materials.
