Pyrene-based ammonium bromides combined with g-CN for the synergistically enhanced fixation reaction of CO and epoxides
A new type of pyrene-based ammonium bromides (PABs) was synthesized via the reaction of bromomethyl pyrene and tertiary amines with different alkyl chains combined with graphitic carbon nitride (g-C 3 N 4 ) through π-π stacking interactions. The new pyrene-based ammonium bromides were investigated b...
