摘要：

     In this presentation, we propose the term “Optochemistry,” a portmanteau combining “optics” and “chemistry.” The difference between photochemistry and optochemistry is described below: Photochemistry primarily treats light as photons (energy particles) and investigates phenomena such as light absorption, emission, excitation energy transfer, photoinduced electron transfer, and various photoreactions including photocatalysis and photoisomerization. In contrast, optics treats light as rays or waves. Although optics and photonics cannot be clearly distinguished, typical applications of optics include optical fibers, optical waveguides, optical resonators, lasers, and optical vortices. As optics is the study of light itself, it does not strictly require the presence of matter; however, recently, the emergence of a new field of optics directly reflects the diverse characteristics of materials.
    Historically, the materials used in optics have been predominantly inorganic such as metals, ceramics, and silica. Although the application scope of organic and polymer materials remains limited, specific technologies such as polymer optical fibers composed of poly(methyl methacrylate) and liquid crystalline  molecules are widely used. Nevertheless, organic materials possess unique structural and functional attributes—including chirality, radical, helicity, supramolecular assembly, and semiconducting properties—some of which are already being integrated into optical applications. Furthermore, concepts from topology, which has long been that debated in mathematics and physics is increasingly being introduced into the field.
    Given the pioneering developments in areas such as light-matter strong coupling and optical vortices, we propose the collective term “Optochemistry” to describe these intersecting domains. In this presentation, we use optochemistry as follows: Chemistry that strongly relates to light with the aspect of wave or beam, and optics that utilize newly appeared chemistry. Under the framework of optochemistry, we outline the precision synthesis of microstructures composed of organic and polymer materials and their subsequent applications in optics.
