Abstract Organic phosphorescence holds significant potential for its important applications in sensors, optoelectronics, and security technologies. However, achieving long‐lived blue phosphorescence, particularly at high temperatures, remains a challenge. In this work, an unusual thermally enhanced is investigated observed readily synthesized polymer (P1), which created by copolymerizing acrylamide with phenyl terpyridine‐containing monomer (M1). Remarkably, P1 exhibits ultra‐long cyan 493 nm lifetime of 1.04 s room temperature 450 when exposed to 150 °C. Experimental simulation results suggest that the high‐temperature originates from activated rotation terpyridine group, triggering conformational transition low‐energy Iso2 high‐energy Iso3 state. Furthermore, heat‐resistant phosphorescent can be easily fabricated into optical waveguide low loss coefficient, making it suitable high‐performance switches. This work provides novel strategy designing high‐temperature‐resistant materials, promising advanced photonic optoelectronic devices.
