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.
