Nanohybrid materials based on nanoparticles of the intrinsically microporous polymer PIM-1 and graphene oxide (GO) are prepared from aqueous dispersions with a reprecipitation method, resulting in surface GO sheets being decorated PIM-1. The significant blueshift fluorescence signals for GO/PIM-1 nanohybrids indicates modification optoelectronic properties presence due to their strong interactions. stiffening Raman G peak (by nearly 6 cm–1) further p-doping PIM. Kelvin probe force microscopy (KPFM) electrochemical reduction measurements provide direct evidence charge transfer between nanosheets. These observations will be importance future applications GO-PIM-1 as substrates promoters catalysis sensing.
