] (PCP-1), exhibiting sensitively thermal-driven, unusual PL/dielectric responses. Notably, the introduction of the 18-crown-6 molecule changed the dynamic thermal motion and exerted a confinement effect through rich hydrogen bonding interactions, thereby inducing structural phase transitions and modulating energy transfer processes. These not only brought about switchable dielectric responses but also resulted in a comprehensive improvement of PL properties, encompassing extended lifetime, doubled quantum yield and temperature-controllable luminescent color. This study offers novel insights into the role of crown ethers in developing smart luminescent materials, holding promising prospects for intelligent recognition and information encryption.
