摘要

Novel organic nanoparticles self-assembled from the hexa[p-(carbonyl glycin methyl ester) phenoxy] cyclotriphosphazene (HGPCP) were prepared by a simple solution method. The as-prepared nanoparticles were extensively characterized by SEM, TEM, XRD, TGA, and fluorescence spectrum. The size of nanoparticles was increased with increasing the HGPCP concentration in solution. The effect of reaction conditions on the particle size and stability was further investigated. Based upon the experimental results, a growth mechanism was proposed for the formation of the nanoparticles. The obtained nanoparticles were highly thermal stable and exhibited strong fluorescent emission, which could be potential candidates for drug-loading carriers and tracer drug delivery.
