Dendronized Encapsulation with Hierarchical Rigidification Enabling Robust Solution Room-Temperature Phosphorescence, Efficient Electroluminescence and Ultralong Afterglow.

ABSTRACT: Organic room-temperature phosphorescence (RTP) materials face a fundamental challenge: their environment-specific phosphorescent behavior fundamentally conflicts with the growing demand for multifunctional materials. To overcome this limitation, a multiscale confinement strategy is developed that integrates intramolecular flexible encapsulation with intermolecular rigid immobilization. Dendronized donor-acceptor molecules are engineered with alkyl-chain-carbazole dendrons to achieve intramolecular encapsulation. This design enables abundant spatial interactions, balancing conformational flexibility (for solution processing) and emission rigidity. Multiscale confinement via molecular aggregation and poly(methyl methacrylate) (PMMA) doping further enhances rigidification. Together, these mec
