The present invention relates to a 10-phenylphenothiazine-based doped organic long afterglow luminescent material and a method for preparing and using the same, comprising a guest molecule X and a host molecule Y, the structure of which is shown in general formula (1), wherein The guest light-emitting molecule X is 10-phenylphenothiazine, and the host-host molecule Y can be an aromatic compound with a twisted configuration. The doped organic long afterglow luminescent material prepared by the invention has high luminous brightness, low dependence of the guest molecule on the host matrix material, and is suitable for aromatic compounds with various twisted structures. In addition, the organic long afterglow material prepared by the present invention has different luminescent colors and lifetimes, and can be applied to the fields of organic optoelectronics, biological imaging and multiple anti-counterfeiting combined with time resolution technology. |
