In this review, we propose a term, 'optochemistry', a combination of optics and chemistry. In comparison with photochemistry that relates to photon aspect of light, optochemistry is a chemistry that relates to optics in which light is considered as wave or beam. Optochemistry and its applications include optical fibers, optical waveguides, organic resonators, lasers, organic polaritonics, light-matter strong coupling, optical vortices, optical manipulation, ultra-high sensitivity optical sensing, and so forth, that relate to the characteristics of molecules and polymers with chirality, spins (radicals), helices, supramolecules, semiconductors etc. The authors expect that the new-and-old optics and chemistry meet and generate a new field of research, and the term 'optochemistry' will gain acceptance to the society in the field of science and technologies.

Stereoisomerism
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...
