Circularly polarized room-temperature phosphorescence enhanced by dynamic cross-linked network fixation

Abstract

Organic ultra-long room temperature phosphorescence (OURTP) has been widely used in applications including encryption and anti-counterfeiting. However, little research has focused on circularly polarised luminescence (CPL) with RTP materials. In order to construct circularly polarised room temperature phosphorescent (CP-RTP) materials with highly efficient luminescent properties, we report on the synthesis of a novel chiral phosphorescent molecule and its immobilization in a dynamically crosslinked Vitrimer film. The lifetime and quantum yield of the green persistent RTP are 895 ms and 9.70%, respectively, and the dissymmetry factor (glum) is up to 0.014. In addition, it exhibits good thermal stimulus response properties, which remain unchanged under repeated multiple cycles of heating/cooling, and it can be further widely used in the field of encryption of optical information and other applications.
