“…Interestingly, both irradiated films, with or without heating, present similar degradation profile above 500 C, that correspond to a weight loss of 50% (Figure S7), considerably lower than non-irradiated films that have a mass loss of 65%. The same thermal behavior was observed for fluorine-functionalized polysulfone which indicates higher thermal stability of the material, 28,29 and is yet another indication in compliance to the proposed mechanism of the formation of a strong interaction between the CF groups with the polysulfone induced by light irradiation.…”

Herein, we present the successful preparation of emissive polysulfone thin films doped with tetracoordinated Tb3+ and Eu3+ complexes, with emission co‐regulated by simultaneous excitation light and heat with controllable emissive pattern. We suggest a ligand driven light induced interaction with polymeric organic host that promotes increased emission in the blue region. Our system lays on dynamic irreversible generation of emissive color from green to cyan. Under commercial 366 nm UV lamp, the unambiguously selected pre‐chosen pattern will emit brighter than non‐irradiated film in the blue region of visible spectrum.
