摘要	Development of photoactive chemical heat storage (PCHS) materials that can be isomerized without ultraviolet light and have outstanding storage performance as well as high rate heat output capability under low temperature conditions is a core issue for effective solar thermal conversion. In this study, we report a novel PCHS material by attaching ortho-tetrafluorinated azobenzene (Azo(TF)) onto reduced graphene oxide (rGO) for photothermal conversion and storage. By applying the strategy of separating the n -> pi* transition of two different configurations of Azo(TF) to the field of PCHS materials, this Azo(TF)-rGO composite not only realizes the isomerization with visible light for two configurations with a long life cycle, but also exhibits excellent fatigue resistance and low temperature high rate heat output capability, which greatly increases its exploitation value. Moreover, the Azo(TF)-rGO composite also shows remarkable heat storage density (Max. 345.8 kJ kg(-1)), power density (Max. 2401.4 W kg(-1)) attribute to the intermolecular hydrogen bond as well as the strong intermolecular interactions arise from the high attachment density. This new Azo(TF)-rGO PCHS material may paves a new way for more effective and efficient solar thermal energy conversion and storage.
