Unconventional fluorescent polymers have attracted wide attention due to their excellent biocompatibility, facile preparation, and unique properties. However, developing high-performance revealing the emission mechanism are still challenging. Herein, explore relationship between chemical structures properties, four hyperbranched poly(silicophosphate) esters (HSiP0-HSiP3) were prepared. Increasing P═O(O)3:Si(O)3 ratios generated enhanced red fluorescence. Experimental theoretical calculation results showed that n-π interactions P═O O/N atoms promoted concentration of negative electrostatic potential spatial electronic communications, then decreased energy gap strong emission. Meanwhile, cluster functional groups a charge isolated groups, which further Additionally, these in bacterial imaging information encryption. Thus, this work provides an efficient method for long-wavelength materials while providing new insights into origin.

Hyperbranched polyphosphate polyesters (HPPs) as a special class of hyperbranched polymers have attracted increased interest and been intensively studied, because peculiar structures, excellent biocompatibility, flexibility in physicochemical properties, biodegradability, water soluble, thermal stability, mechanical properties. HPPs can be divided into phosphates monomers end groups. In this article, the classification, general synthesis, modifications, applications HPP are reviewed. addition, recent developments application described, such modified or functionalized by capping hypergrafting to improve performances polymer blends, coatings, flame retardant, leather. Furthermore, modifications biomedical materials, drug delivery bone regeneration were discussed. summary, enlarges its range improves performance compared with conventional polymer. future, more new composite materials will developed through technique. This review provide useful theoretical basis technical support for development material.
