Conjugated microporous polymers (CMPs) are usually obtained as amorphous
or semicrystalline powders. Their insolubility and nonprocessability
are considered as key bottlenecks that impede CMP applications. In this
study, light-emitting, nanofibrous films were fabricated by
electrospinning CMP/poly(lactic acid) (PLA) mixtures. The resulting
nanofibrous films show a high flexibility combined with high porosity
and surface-area-to-volume ratios. The CMP-based nanofibrous films have
been used as sensitive sensors in the detection of nitroaromatic and
benzoquinone vapors as well as oxidizing metal ions. Moreover,
4-iodophenyl-substituted graphene sheets were used as templates for
growing CMP/graphene sandwiches. The graphene-based CMP (G-CMP)
sandwiches are characterized by high surface areas and aspect ratios.
Furthermore, hierarchically porous two-dimensional carbon nanosheets
were obtained by pyrolysis of these carbon-rich G-CMP hybrids. The
resulting carbon nanomaterials show excellent supercapacitor behavior
with a 48% increased capacitance if compared to porous carbons without
the graphene template.
