High‐Performance Organic Ultralong Room Temperature Phosphorescence Based on Biomass Macrocycle
East China University of Science and Technology
Abstract
The pursuit of sustainable, high-performance organic ultralong room temperature phosphorescence (OURTP) materials with stimulus-responsive properties presents a significant and enticing yet formidable challenge. Herein, an efficient strategy to confining boric acid-based compounds into biomass macrocycle γ-cyclodextrin through multiple interactions is developed, enabling the construction of high-performance and multicolor OURTP doped systems. The synergistic effects of strong hydrogen bonding, C─O─B covalent cross-linking, and host-guest encapsulation significantly suppress non-radiative transition, culminating in an extraordinary lifetime and excellent phosphorescence quantum yield of 4.65 s and 32.8%,…
