摘要
Highly cross-linked and monodisperse polyphosphazene nanoparticles exhibiting strong fluorescence with oxyresvertrol structure was facilely generated via a one-pot prediction polycondensation of hexachlorocyclotriphosphazene and oxyresveratrol. The results reveal that the diameter of the microspheres can be well adjusted (typically in a range from 200 to 400nm). Attractively, the as-prepared nanoparticle with oxyresveratrol structure possess outstanding disperse ability in both aqueous and organic media. Moreover, it exhibits significantly enhanced fluorescent intensity and outstanding photobleaching stability under ultraviolet-visible irradiation, owing to the highly cross-linked and organic-inorganic hybrid structure. Due to these superior properties and novelty of our synthesized material, it has shown great potential in application as fluorescent labels, carriers and potent biomaterials in drug delivery.
