chemical light energy storage

Molecular solar thermal (or MOST) energy storage works on the principle of storing energy in chemical bonds. It relies on specially designed photosensitive molecules that undergo reversible structural change known as Dewar isomerization.

Photochromic molecules can store light energy, but could they also convert it into heat? That is the challenge recently met by scientists from the CNRS and ENS Paris-Saclay 1 2 . The team identified a mechanism by which these molecules release this energy in thermal form, and can subsequently be

We present here a group of Azo-BF 2 photoswitches that store and release energy in response to visible light irradiation. Unmodified Azo-BF 2 switches have a planar structure with a large π-conjugation system, which hinders E–Z isomerization when in a compacted state. To address this challenge, we

Curved molecules that absorb sunlight, store the energy, and re-release it as heat are pushing the boundaries in solar thermal storage technology. In a recent study published in the journal Chem, researchers revealed curved anthracene derivatives—organic molecules found in coal tar —that undergo

Certain organometallic molecules undergo a reaction upon exposure to light that is reversible with either a catalyst or heat. In some cases a considerable amount of energy can be stored, as was shown for example in the work of Vollhardt in for fulvalenes. In the Ru case shown in this figure

Storing solar energy in molecules and converting it

These molecules, which are very resistant to light, are part of a family of original photosensitive switches that store solar energy in chemical form, and then transform it “on demand” into thermal energy.
