摘　　要：设计合成了一种具有室温光致固液转换性能的偶氮苯衍生物1-[4-(烯丙氧基)苯基]-2-(对甲苯基)二氮烯(AD-Azo)用于制备太阳热能燃料(STFs),结合其固液转换过程中的相变潜热,较大幅度提高了偶氮苯衍生物的能量存储密度.在光/热诱导下使其与普通商用布料结合,制备了环境友好、即用式柔性太阳热能燃料器件AD-Azo STF.利用织物内分子间超分子作用(氢键),增强了能量存储密度和储能寿命,使其总储能密度高达199.12 J/g,储能半衰期为50 h.该柔性AD-Azo STF器件具有良好的柔韧性、溶剂稳定性和循环使用性,在环境友好型太阳热能燃料中具有良好的应用前景.A new kind of azobenzene derivative 1-[4-(allyloxy)phenyl]-2-(p-tolyl)diazenyl(AD-Azo)with room temperature photo-induced solid-liquid transition performance was designed and synthesized for solar thermal fuels(STFs)applications.At the same time,the energy storage density of the azobenzene derivative was greatly improved due to the latent heat of phase transition during solid-liquid conversion.Under light or heat induction,AD-Azo was combined with ordinary commercial fabric to prepare an environmentally friendly,ready-to-use flexible STF device.Moreover,there is a supramolecular interaction(hydrogen bond)between molecules in the fabric,which enhances the energy storage density and energy storage life.The total energy storage density of the STF device is as high as 199.12 J/g,and the energy storage half-life is 50 h.In addition,this flexible AD-Azo STF device possesses good flexi-bility,solvent stability and recyclability,which has potential application prospects in environment-friendly STFs.
