Storing energy with molecular photoisomers

Joule, Год журнала: 2021, Номер 5(12), С. 3116 - 3136

Опубликована: Ноя. 22, 2021

Some molecular photoisomers can be isomerized to a metastable high-energy state by exposure light. These molecules then thermally or catalytically converted back their initial state, releasing heat in the process. Such reversible photochemical process has been considered for developing solar thermal (MOST) systems. In this review, we introduce concept, criteria, and state-of-the-art of MOST systems, with an emphasis on three most promising systems: norbornadiene/quadricyclane, E/Z-azobenzene, dihydroazulene/vinylheptafulvene. After discussing fundamental working principles, focus design strategies improving energy storage performance, remaining challenges, potential areas. Finally, summarize current incorporation into functional devices conclude perspective challenges future directions.

Visible-Light-Activated Heteroaryl Azoswitches: Toward a More Colorful Future

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(29), С. 19609 - 19620

Опубликована: Июль 11, 2024

Azobenzenes (Ph-N═N-Ph) are known as the most widely studied molecular photoswitches, and recent rise of azoheteroarenes (Het-N═N-Ph or Het-N═N-Het) offers great opportunities to advance this already mature field. A common limitation is that azo-switches generally require harmful UV light for activation, which hinders their application across various fields. Despite efforts in developing visible-light azobenzenes over past few decades, potential heteroaryl azoswitches remains largely unexplored. This Perspective summarizes state-of-the-art advancements azoswitches, covering design strategies, structure-property relationship, applications. We highlight distinctive advantages research development switches. Furthermore, we discuss challenges emerging field propose solutions address crucial issues such spectral red-shift thermal half-life. Through paper, aim provide inspiration further exploration field, anticipation growing prosperity bright future azoheteroarene photoswitches.
