Organic long-persistent luminescence(LPL)materials,featuring low preparation cost,eco-friendly syn-thesis,and easy modification of functional groups,have exhibited extensive applications in information encryption,anti-counterfeiting,and biological imaging.Several design strategies including crystallization-inducement,H-aggregation,and host-guest doping to enhance persistent-room-temperature phosphores-cence(RTP)effect by precisely controlling intersystem crossing(ISC)constant and suppressing nonra-diative decay rates,those are important strategies to enable LPL performance.Among the strategies,re-searchers have made several efforts to enhance persistent-RTP effect by host-guest interaction,in which the host matrices provide a rigid environment for phosphor guest molecules.The interaction of the lu-minescent guest molecules with the host matrix can effectively reduce the vibration and rotation of the luminescent molecules,and suppress the non-radiative inactivation,thereby improving the phosphores-cence quantum yield.This review aims to summarize several design strategies of pure organic LPL ma-terials based on persistent-RTP effect through host-guest interaction,and describe some applications of pure organic LPL materials in different fields.
