Abstract

This review summarizes recent advances in unconventional hyperbranched luminescent polymers containing Si， P， and B. These luminescent polymers form three-dimensional hyperbranched topological structures through organic-inorganic hybrid units such as Si-O-C， P-O-C， and B-O-C. Internally enriched with heteroatoms bearing lone pairs（e.g.， O， N， S）， these heteroatoms spontaneously form clusteroluminogens through spatial n/π interactions， multiple hydrogen-bond networks and nonmetallic coordination bonds. Exhibiting excellent biocompatibility， these luminescent materials demonstrate significant application potential in fields such as drug-controlled-release visualization， cellular bioimaging， and advanced information encryption. We focus on discussing the luminescence mechanism and structure-property relationships of this luminescent material， while identifying current challenges and future research directions.
