A new hypercrosslinked supermicroporous polymer, with scope for sulfonation, and its catalytic potential for the efficient synthesis of biodiesel at room temperature

A new supermicroporous polymer with a BET surface area of 913 m² g⁻¹ has been synthesized via Friedel–Crafts alkylation between carbazole and α,α′-dibromo-p-xylene.
