Synthesis of a highly conductive coordination polymer film via a vapor-solid phase chemical conversion process

A novel vapor-solid phase chemical conversion process is reported here to synthesise high-quality films of the conductive coordination polymer (c-CP) Ag₅BHT (BHT = benzenehexanothiolate), which has the potential to be applied for the synthesis and processing of c-CP electronic devices. This approach involves reacting a silver oxide precursor and an H₆BHT linker in an isopropanol solvent vapor atmosphere to obtain Ag₅BHT thin films with controllable thickness (100-300 nm). The as-synthesized Ag₅BHT thin films exhibit conductivities as high as 10 S cm^-1. Additionally, under field-effect modulation, these nanofilms demonstrate remarkably high charge mobility (38 cm² v^-1 s^-1).
