Light-Driven Chemistry: Photoswitch in RNA Activity Control and Development of Photoredox Catalysis

This dissertation is structured into two principal segments. The initial segment elucidates a series of synthetic works involving artificial molecules, specifically featuring the photosensitive azobenzene. These molecules facilitate remote control over the structure and functionality of biomolecules, with subsequent applications in regulating biological processes. The latter segment concentrates on the design and enhancement of organic photocatalysts, utilizing traditional acridine ions as a foundation. This section details the development of diverse organic photocatalyst-promoted processes, including photo Lewis acid catalysis, photo Brønsted acid catalysis, and photoredox reactions.
