高分子长余辉发光材料具有无定态结构、可加工性能好、发光寿命长、成本低廉等优点,对拓展纯有机长余辉发光材料的应用具有重要意义。为了实现高分子发光材料的长余辉发射,当前主要是利用杂原子或者重原子的自旋轨道耦合作用,提高单/三线态激子间的系间窜越能力;高分子基质中的氢键、卤键、离子键等分子内和分子间相互作用为磷光基团提供刚性环境,抑制其三线态激子的非辐射跃迁和猝灭。基于此,本文综述了近年来高分子长余辉发光材料的研究进展,以及在未来发展过程中面临的机遇与挑战。
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.
