Reversible metastable-state photoacids (RMSP) are the molecules that transform to high-acidity metastable states upon irradiation, and change back to low-acidity ground states in the dark. Due to the long lifetime of the metastable state, a large pH change can be reversibly generated by irradiation with moderate intensity (LED, outdoor light in a sunny day, etc.). In this presentation, the principle of designing RMSP will be discussed. The recently developed RMSPs and their potential applications in chemical, material, and biological areas will be presented. Challenges of developing RMSPs with desirable properties and materials containing RMSPs for different applications will also be discussed.
