文摘

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.
