A series of liquid and photoliquefiable azobenzene (Azo) derivatives (Azo-C-Br) have been synthesized for molecular solar thermal fuels. Each of the liquid and photoliquefiable azo derivatives shows a high degree of isomerization, a fast isomerization rate, a long half-life, an appropriate energy storage density, and a solvent-free "charging" and "discharging" process. The photoliquefied azo derivatives can isomerize upon UV light irradiation at low temperatures to give the "UV-charged" azo ones. Therefore, the phase transition enthalpy is stored simultaneously along with the isomerization enthalpy. The "UV-charged" azo derivatives are capable of releasing heat under the manipulation of blue light.
一系列用于分子太阳能热燃料的液体和可光液化的偶氮苯（Azo）衍生物（Azo-C-Br）已被合成。每种液体和可光液化的偶氮衍生物都表现出高度的异构化、快速的异构化速率、长的半衰期、合适的储能密度以及无溶剂的“充电”和“放电”过程。光液化的偶氮衍生物在低温下经紫外光照射可异构化，得到“紫外充电”的偶氮衍生物。因此，相变焓与异构化焓同时被储存。“紫外充电”的偶氮衍生物能够在蓝光的作用下释放热量。
