Abstrakt

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.
