Abstract:
Stimuli-responsive photochromic units have emerged as one of the key components in the development of multi-responsive switches, optoelectronics, biomedical sciences and many more. The photoswitchability of such compounds depends greatly on the molecular structure, where association of metallic species is found to produce fascinating results. This review is a comprehensive report of all such photoswitchable metal-bounded molecules with group 8 metals within a span of last six years (2018-2024). Apart from the regular photoswitching phenomenon, this review focusses on the enhanced tunability, structural flexibility and perturbation in the photophysical properties of the group 8 metal-based photoswitches. Previous reviews in this field have either focused on some specific applications or have been general with the type of metal incorporations. Herein, we have constructed the review with group 8 organometallic photochromic compounds that possess a wide range of real-life applications. Designing strategies, structure-property relationships and application-oriented approach of the photochromic organometallic compounds have been elucidated categorically for building up a comprehensive idea about this modern developing field of research.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
