Stable Carbon Dots from Microwave-Heated Carbon Nanoparticles Generating Organic Radicals for In Situ Additions

Carbon dots (CDots) are small carbon nanoparticles with effective surface passivation by organic functionalization. In the reported work, functionalization of preexisting N-ethylcarbazole (NEC) was achieved NEC radical addition. Due to major difference in microwave absorption between and species such as NEC, could be selectively heated via irradiation enable hydrogen abstraction generate radicals, followed situ additions radicals nanoparticles. The resulting NEC-CDots were characterized microscopy spectroscopy techniques including quantitative proton 13C NMR methods. optical spectroscopic properties dot sample found largely same those CDots from other schemes. high structural stability benefiting addition is highlighted discussed.
