Enhanced Singlet Oxygen Generation in Oxidized Graphitic Carbon Nitride for Organic Synthesis

Thumbnail image of graphical abstract

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