New highly nucleophilic homogeneous and heterogeneous catalysts based on the 3,4-diaminopyridine scaffold are reported for halogen-free cycloaddition of CO2 to epoxides.
Covalent triazine frameworks (CTFs) synthesized through the nucleophilic substitution of 4,4′-bipyridine on carbon atoms cyanuric chloride were studied as fluorescent sensors.
