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.
