Abstract
The solvothermal reactions of copper(I) tert-butylthiolate (CuStBu) with 1/3 equiv. of dppe [dppe = bis(diphenylphosphino)ethane] or bix [bix = 1,4-bis(imidalzole-1-ylmethyl)benzene] in CH3CN led to the formation of two cluster-based coordination polymers [(CuStBu)4(dppe)] n (1) and [(CuStBu)6(bix)] n (2). Single-crystal X-ray diffraction studies reveal that 1 and 2 feature 1D zigzag polymeric chains which contain rare (CuStBu)4 or (CuStBu)6 clusters as connecting junctions and dppe or bix as linkers. The title compounds show optical transitions with band gaps of ∼3.18 eV for 1 and ∼2.81 eV for 2. Compounds 1 and 2 exhibit strong photoluminescence with the peaks maximum at 603 and 629 nm respectively.
Graphical Abstract
Two 1D zigzag polymers [(CuStBu)4(dppe)] n (1) and [(CuStBu)6(bix)] n (2) [dppe = bis(diphenylphosphino) ethane] or bix [bix = 1,4-bis(imidalzole-1-ylmethyl)benzene] have been synthesized by solvothermal reactions using copper(I) tert-butylthiolate CuStBu as the starting material. Compounds 1 and 2 contain rare (CuStBu)4 and (CuStBu)6 clusters as connecting nodes and dppe or bix as bridging ligands. The title compounds show optical transitions with band gaps of ∼3.18 eV for 1 and ∼2.81 eV for 2. Both 1 and 2 exhibit strong photoluminescence with the peak maximums at 603 and 629 nm, respectively.
