Conjugatedmicroporous polymers (CMPs) are usually obtained asamorphous or semicrystalline powders. Their insolubility and nonprocessabilityare considered as key bottlenecks that impede CMP applications. Inthis study, light-emitting, nanofibrous films were fabricated by electrospinningCMP/poly(lactic acid) (PLA) mixtures. The resulting nanofibrous filmsshow a high flexibility combined with high porosity and surface-area-to-volumeratios. The CMP-based nanofibrous films have been used as sensitivesensors in the detection of nitroaromatic and benzoquinone vaporsas well as oxidizing metal ions. Moreover, 4-iodophenyl-substitutedgraphene sheets were used as templates for growing CMP/graphene sandwiches.The graphene-based CMP (G-CMP) sandwiches are characterized by highsurface areas and aspect ratios. Furthermore, hierarchically poroustwo-dimensional carbon nanosheets were obtained by pyrolysis of thesecarbon-rich G-CMP hybrids. The resulting carbon nanomaterials showexcellent supercapacitor behavior with a 48% increased capacitanceif compared to porous carbons without the graphene template. [ABSTRACT FROM AUTHOR]
