Assembly of a 3D chiral Cu(I) metal–organic framework based on 4,5-dicyanoimidazole: CD spectrum, luminescence and selective gas adsorption

•One novel chiral Cu(I) metal–organic framwork has been obtained based on nitrobenzene.•The 3D metal–organic framework can be regarded as a PtS net with the vertex symbol of {42.84}.•The gas adsorption/desorption experiments of complex 1 have been measured at 77 K.

One chiral Cu(I) metal–organic framework {[Cu(DCI)]·0.1Cyc·0.45Nbenz}n (1) (HDCI = 4,5-dicyanoimidazole, Cyc = cyclohexanol, Nbenz = nitrobenzene), was obtained under solvothermal condition. Complex 1 presents a 3D chiral porous framework with 38.2% porosity. The 3D metal–organic framework can be regarded as a PtS net with the vertex symbol of {42.84}. The gas adsorption/desorption experiments of complex 1 have been measured at 77 K. Moreover, the CD spectrum and photoluminescent behavior of complex 1 have been studied.
