Molecular Solar Thermal (MOST) Energy Storage—Definitions and Requirements Revisited Molecular solar thermal storage (MOST) systems have recently regained great interest after a period of intense research around five decades ago. This perspective clarifies the nomenclature, and intro...

New perspective out! We revisit the foundations of molecular solar thermal storage (MOST) and introduce the term „mostophore“ to describe molecular units that harvest and store solar energy as heat. ☀️ Moreover, we highlight key directions for future solar-energy research.

Electrochemistry of Azobenzenes and Its Potential for Energy Storage Azobenzenes are promising materials for energy storage due to their reversible photoisomerization and redox properties. Given the critical role of redox behavior in the latter application, an investigation of their redox processes is essential. We propose a classification of azobenzenes into two categories: benzenoid-type and quinoid-type, based on the mechanism of their oxidation. Benzenoid-type compounds have been extensively studied due to their reversible reduction. Quinoid-type compounds exhibit oxidative and reductive versatility, making them promising for further research in energy storage.
