Abstract: ABSTRACT The research introduced methyl groups into the Hyperbranched polysiloxane (HBPSi) structure at various synthesis ratios. By leveraging the steric hindrance and hydrophobicity of methyl groups, the formation of highly branched three‐dimensional architectures is expected to be promoted. Compared with traditional linear polymers, such structures generally exhibit superior solubility, lower melt viscosity, and higher reactivity. The chemical structures and properties of the synthesized HBPSi derivatives were characterized using proton nuclear magnetic resonance ( 1 H‐NMR) spectroscopy, Fourier transform infrared (FTIR) spectrum, photoluminescence (PL) spectrum, and thermogravimetric analysis (TGA). Based on the established structure‐fluorescence property relationships of the as‐synthesized HBPSi derivatives, this study further investigates their aggregation‐induced emission (AIE) mechanisms. This research aims to provide both theoretical and practical foundations for the preparation and functional optimization of AIE‐active polymers.
