A dihydroazulene-based aggregation-induced emission system is developed and systematically investigated. The light-driven ring-opening and heat-driven closing processes endow it with controllable and quantitively described photofluorochromic properties. Accordingly, a rewritable4Dinformationencryptionsystem with dynamic patterns is demonstrated, which shows a considerable data-storage capacity
