Recently discovered designs of solid-state molecular solar thermal energy storage systems are illustrated, including alkenes, imines, and anthracenes that undergo reversible [2 + 2] and [4 + 4] photocycloadditions for photon energy storage and release. The energy storage densities of various molecular designs, from 6 kJ mol to 146 kJ mol (or up to 318 J g), are compared and summarized, along with effective strategies for engineering their crystal packing structures that facilitate solid-state reactions. Many promising molecular scaffolds introduced here highlight the potential for achieving successful solid-state solar energy storage, guiding further discoveries and the development of new molecular systems for applications in solid-state solar thermal batteries.
文中展示了最近发现的固态分子太阳能热能存储系统的设计，包括通过可逆的[2 + 2]和[4 + 4]光环加成反应来进行光子能量存储和释放的烯烃、亚胺和蒽。文中比较并总结了各种分子设计的储能密度，范围从6 kJ/mol到146 kJ/mol（或高达318 J/g），同时还介绍了用于设计其晶体堆积结构以促进固态反应的有效策略。这里介绍的许多有前景的分子支架突出了实现成功的固态太阳能存储的潜力，为进一步的发现以及开发用于固态太阳能热电池应用的新分子系统提供了指导。
