|a Achieving high phosphorescence efficiency and photo-activated ultralong organic phosphorescence (UOP) based on the same molecule remains a formidable challenge. Here, a concise strategy is proposed to obtain highly efficient and photo-activated RTP by doping aromatic heterocyclic derivatives into different polymers. Aromatic heterocyclic derivatives are doped into PAM, PVA, or PAA polymers to produce high phosphorescence efficiency. Impressively, the highest phosphorescence quantum yield can reach up to 66.2% at room temperature, which can be attributed to isolating the chromophore to reduce the excimer and the rigid environment from the polymer to restrict the non-radiative transitions. In addition, phosphorescence emission color can be tailored from green to deep blue by varying the guests. After aromatic heterocyclic derivatives are doped into PDMA or PVP, the phosphorescence lifetime is prolonged from 1.2 to 578.6 ms. These polymers are successfully applied to multicolor displays and high-level information storage. This work provides a reasonable strategy to develop highly efficient and photo-activated RTP materials based on the same molecule
