Luminescent cocrystals have been received much attention in fluorescence imaging and sensor application. In this work, we report that the high-quality chiral luminescent cocrystal can be obtained through a molecular self-assembly process of 2,20-binaphthol and 2-（3-pyridyl）-1 H-benzimidazole. The assembly modes and stacking fashions of as-obtained cocrystal were determined by single crystal X-ray diffractometer. The structure and optical properties of the cocrystals were characterized by fluorescence emission, fluorescence decay, Raman and circular dichroism spectra. The results show that both the pristine co-assembled units（R-BINOL and S-BINOL） give rise to the R conformation within the final cocrystal, suggesting that the formation of cocrystal can be an effective way to achieve R/S-isomeric transformation of 2,20-binaphthol. It is also expected that the co-crystallization approach has much flexibility and potential applications for the design and selective formation of chiral luminescent materials.

Reaction of sulfonylated binaphthol [2-hydroxy-2＇-tosyloxy-l,l-binaphthyl （la, Ts-Binol） or 2-hydroxy-2＇- （phenylsulfonyloxy）-l,l-binaphthyl （lb, Ps-Binol）] with 1 equiv, of ZnEt2 afforded zinc complexes [（Ys-Binol）ZnEt]2 （2a） and [（Ps-Binol）ZnEt]2 （2b）. Further reaction of zinc complexes 2a and 2b with benzyl alco- hol （BnOH） gave the zinc benzyloxide [（Ts-Binol）2Zn2（OBn）2]2 （3a） and [（Ps-Binol）2Znz（OBn）2]2 （3b）. Alterna- tively, the zinc benzyloxides 3a and 3b could also be obtained by reaction of compound la or lb with Zn（OBn）2 （in situ reaction of ZnEt2 and BnOH）. The complexes were fully characterized by elemental analyses and spectroscopic analyses, and complexes 2a, 2b and 3a were further characterized by single-crystal X-ray analyses. The catalytic activities of these zinc complexes towards ring-opening polymerization of ε-caprolactone and D,L-lactide were studied.
