New charge transfer-based organic room temperature phosphorescent trace doping systems.

Abstract

A series of room temperature phosphorescent doping systems were constructed. Benzothiazole groups containing heteroatoms (S, N) and heavy atoms (Br) were applied as the host. Their charge-transfered luminescence mechanism was revealed by molecular dynamics simulations and molecular cluster calculations. Additionally, BCN/BT's excellent anti-counterfeiting performance demonstrated their application potential.
