“…Photochromic mechanisms are usually explained by pericyclic reactions, [ 54 ] cis‐trans isomerizations, [ 55 ] dissociation, [ 56 ] intramolecular hydrogen transfers [ 57 ] or group transfers, [ 58 ] and electron charge transfers. [ 59 ] Pericyclic reaction is an organic process involving rearrangement or additional reactions where the transition state of the molecule has a cyclic geometry.…”

“…Hydrogen photochromism was demonstrated in the V 2 O 5 xerogels using a dispersant called dimethylformamide (DMF) as a hydrogen donor. [ 57 ] DMF was adsorbed on the V 2 O 5 surface along the formation of the xerogel from the sol containing the hydrogen donor. DMF molecules bonds to the oxide surface by donor–acceptor and hydrogen bonds, allowing easy detachment of hydrogen atoms under the UV irradiation.…”

Limited levels of UV exposure can be beneficial to the human body. However, the UV radiation present in the atmosphere can be damaging if levels of exposure exceed safe limits which depend on the individual the skin color. Hence, UV photochromic materials that respond to UV light by changing their color are powerful tools to sense radiation safety limits. Photochromic materials comprise either organic materials, inorganic transition metal oxides, or a hybrid combination of both. The photochromic behavior largely relies on charge transfer mechanisms and electronic band structures. These factors can be influenced by the structure and morphology, fabrication, composition, hybridization, and preparation of the photochromic materials, among others. Significant challenges are involved in realizing rapid photochromic change, which is repeatable, reversible with low fatigue, and behaving according to the desired application requirements. These challenges also relate to finding the right synergy between the photochromic materials used, the environment it is being used for, and the objectives that need to be achieved. In this review, the principles and applications of photochromic processes for transition metal oxides and hybrid materials, photocatalytic applications, and the outlook in the context of commercialized sensors in this field are presented.
