Synthesis and crystal structure of pyrazine-based one-dimensional perovskite compound

Here, the crystal synthesis, crystal structures, optical band gaps and application in devices of (C4N2H6)PbI3 and (C4N2H6)PbBr3 are researched and discussed. Novel hybrid 1D perovskite single crystals based on pyrazine were obtained by reacting the organic cation C4N2H6 with lead iodide and bromide. The band gaps of (C4N2H6)PbI3 and (C4N2H6)PbBr3 compounds are 2.71 and 2.82 eV, respectively, which consistent with the structure distor-tion. The 1D crystals of (Py)PbI3 and (Py)PbBr3 assisted the device efficiency from 20.15% to 22.12 and 22.38%, respectively.
