Light-Controlled Proton ChemistryLight-Controlled Proton Chemistry

The proton, the smallest positive ion in chemistry, is involved in many chemical processes. The Liao group has discovered that metastable-state photoacids can reversibly change the proton concentration based on light exposure. This type of photoacid has been utilized to control various proton reactions and found applications in polymer preparation, biosensors, microbial fuel cells, photochromic materials, and nanomaterials. Dr. Liao published an invited review article in the prestigious journal Accounts of Chemical Research (2017, 50(8), 1956-1964). The review summarizes the works by his and other groups around the world on the design and applications of metastable-state photoacids.
