Abstract

Two highly porous and semiconducting pyrene-quinoxaline-derived benzimidazole-linked polymers have been synthesized and fully characterized. The polymers have a high surface area (SABET = ∼950 m2 g−1) while their electronic structure studies reveal bandgaps in the semiconducting range (2.02 and 2.16 eV) and emissions in the orange-red region (600 and 630 nm). The high surface area and optical properties make these polymers very interesting for gas storage, optoelectronics, and sensing applications.
