Abstract Polymeric room‐temperature phosphorescence (RTP) materials exhibiting facile processability, high thermal stability, and environmental compatibility have garnered considerable attention. However, achieving excellent stretchability in simultaneity with ultralong RTP remains challenging because most polymers rely on rigid structures inherently poor tensile properties. Herein, a stretchable, polyurethane is prepared through copolymerizing novel phosphor dihydroxy‐functionalized indolocarbazole, 4,4′‐methylenedicyclohexyl diisocyanate (HMDI), poly(tetrahydrofuran) (PTMEG 2000), adipic dihydrazide (AD). The covalently bonded to the backbone, which facilitates stabilization of triplet excitons achieves RTP. obtained copolymers exhibit maximum strain 1400% longest lifetime 1888 ms. Additionally, polyurethanes different afterglow colors are by varying molecular structure phosphor. Notably, also display resistance humidity heat. This work may provide new option for development materials.
