Six TAT-based luminophores with different peripheral groups have been designed and synthesized. Dispersing them into rigid PPh3 matrixes triggered persistent RTP through a host-guest strategy. Among the six luminophores, the 6-TAT-CN/PPh3 co-crystalline films obtained the highest phosphorescence yield of 29.35% with a phosphorescence lifetime of 0.76 s. In addition, these host-guest materials showed great potential for multi-level dynamic data encryption and anti-counterfeiting.
