Abstract Photochemical phase transition is an effective strategy to realize photothermal conversion and multi-source energy storage. Azobenzene molecule with photo-induced reverse solid-liquid transitions was synthesized through molecular design, achieving multi-source storage for both solar and environmental thermal energy. The energy was stored in the molecular conformation, and could be rapidly released in the form of heat under external stimulation. The molecule exhibited a low crystallization point (cis
