Experimental data reveal that the incorporation of carbonyl groups into polymer matrix can significantly enhance singlet oxygen ( 1 O 2 ) generation and suppress production of other reactive oxygen species. Excitonic processes investigated by phosphorescence spectroscopy reveal enhanced triplet‐exciton generation in the modified g‐C 3 N 4 , which facilitate 1 O 2 generation through an energy transfer process. Benefiting from this, the modified g‐C 3 N 4 shows excellent conversion and selectivity in organic synthesis.
