An Azobenzene-Based Liquid Molecular Solar Thermal (MOST) Storage System-Energy Carrier and Solvent.

ABSTRACT: A molecular solar thermal (MOST) storage systems is based on capturing solar energy via photoisomerization, which can be released later as thermal energy. Herein, the low viscosity, green light active, 2,6-difluoroazobenzene is introduced, which can be efficiently irradiated, pumped, and handled in its neat state. Synthesis as well as isomerization can be done conveniently in a continuous flow setup. Storage densities of 218 kJ kg^-1 for 100% (Z)-isomer (137 kJ kg^-1 after green light irradiation) are the highest compared to other liquid azobenzenes (ABs). Additionally, the irradiation with green light and the processibility in the neat state make this compound a promising candidate for energy storage applications. Furthermore, the liquid AB can be employed as a MOST-ac
