Fluorescent organic nanoparticles self-assembled from hexa[p-(carbonyl glycin methyl ester) phenoxy] cyclotriphosphazene in solution

► A desolvation method is developed for self-assembly of nanoparticles from HGPCP. ► The size of nanoparticles is concentration dependent. ► The nanoparticles exhibit highly thermal stability and fluorescent emission. ► The self-assembly is driven by hydrogen bonds with participation of water molecules.
