Abstract
En 中文
Organic room-temperature phosphorescence (ORTP) polymers hold substantial promise for optical multiplexing in high-security applications, yet the integration of holographic functionality is fundamentally limited by a trade-off between high diffraction efficiency and intense phosphorescence. Herein, we present a dynamic covalent strategy using oxime urethane chemistry, which enables the design of ORTP polymers through three-stage orthogonal crosslinking reactions. The oxime urethane can undergo post-crosslinking with pendent hydroxyl groups in the polyurethane networks, which affords significantly greater flexibility in modulating the holographic grating morphology and crosslinking density of polymer networks. As a result, a novel ORTP holographic plastic is achieved, exhibiting a remarkable 329% enhancement in diffraction efficiency while maintaining high phosphorescence intensity. This system enables bright 3D holographic imaging and sustains long-lived phosphorescent displays, both without crosstalk. Overall, this work illustrates how dynamic covalent chemistry can be leveraged to simultaneously achieve superior holographic and phosphorescent properties within a single polymer system, offering a robust design paradigm for multifunctional optical materials suited to advanced anticounterfeiting and information encryption.
