Materials with pure organic circularly polarized afterglow (CPA) are notable for their multi-dimensional optical characteristics due to time-dependent and polarization properties. These attributes endow them exceptional appeal value in the realms of information storage anti-counterfeiting measures. Currently, there limited studies on multi-color CPA materials both high dissymmetry factor (glum) values long lifetimes. Here, we propose a universal strategy prepare spanning from blue red, an ultralong emission lifetime over 6 s glum up 100 (the highest was 1.90). This leverages mechanism radiative energy transfer selective reflection cholesteric liquid crystals. Through multi-layered assembly, our method offers simple means constructing encryption.
