Abstract

Experimental data reveal that the incorporation of carbonyl groups into polymer matrix can significantly enhance singlet oxygen (1O2) generation and suppress production of other reactive oxygen species. Excitonic processes investigated by phosphorescence spectroscopy reveal enhanced triplet-exciton generation in the modified g-C3N4, which facilitate 1O2 generation through an energy transfer process. Benefiting from this, the modified g-C3N4 shows excellent conversion and selectivity in organic synthesis.
