Fluorescent aminoarylcyclotetraphosphazenes

One-pot and ultrafast synthesis of nitrogen and phosphorus co-doped carbon dots possessing bright dual wavelength fluorescence emission

“…22 The fluorescence properties of a number of arylsubstituted phosphazenes of different ring sizes were reported (for the optical properties of the N,P-CDs, see also below). 23,24 Thus, the presence of phosphazene-like structures is not unlikely. Additionally, ammonium phosphate functionalities could provide the excellent water-solubility of the N,P-CDs.…”
