高分子长余辉发光材料研究进展

Polymers with long-lived persistent luminescence have exhibited the characteristics of amorphous structure, excellent process properties, long luminescence lifetime and low cost, which were important to develop the potential application for the pure organic long-lived persistent luminescent materials. In order to obtain the polymers with long-lived persistent luminescence, the current method was to utilize the spin-orbit coupling of heteroatom or heavy atom to improve the inter-system crossing channels of singlet and triplet excitons; and polymer matrix with intramolecular and intermolecular interactions of hydrogen bond, halogen bonding, ionic band and so on will provide the rigid environment for phosphorescent groups to restrain the non-radiative transition and quenching of triplet excitons. Based on these, this article reviewed the research progress of polymers with long-lived persistent luminescence in recent years, as well as put forward the opportunities and challenges in the future development process.
