Abstract

Abstract : Experimental data reveal that the incorporation of carbonyl groups into polymer matrix can significantly enhance singlet oxygen ( 1 O2 ) generation and suppress production of other reactive oxygen species. Excitonic processes investigated by phosphorescence spectroscopy reveal enhanced triplet‐exciton generation in the modified g‐C3 N4, which facilitate 1 O2 generation through an energy transfer process. Benefiting from this, the modified g‐C3 N4 shows excellent conversion and selectivity in organic synthesis.
