Claudia Turro is an American inorganic chemist who is the Dow Professor of Chemistry at The Ohio State University (OSU). Since July 2019 she has been the Chair of the OSU Department of Chemistry and Biochemistry. [1] She was elected Fellow of the American Chemical Society in 2010 [2] and is a member of the American Academy of Arts and Sciences (2023) [3] and the National Academy of Sciences (2024). [4]
Claudia Turro earned her B.S. with Honors from Michigan State University in 1987. She completed her Ph.D. in 1992 at the same institution, where she collaborated with Daniel G. Nocera and George E. Leroi. Following this, she was awarded a Jane Coffin Childs Memorial Fund for Medical Research Postdoctoral Fellowship, which allowed her to conduct postdoctoral research at Columbia University with Nicholas J. Turro (no relation) from 1992 to 1995. [5]
Turro joined the faculty of The Ohio State University in 1996. [5] She and her group study light-initiated reactions of metal complexes, with applications in photochemotherapy (PCT) and treatment of diseases, luminescent sensors, and solar energy conversion. They investigate the excited states of mononuclear and dinuclear transition metal complexes to enhance their reactivity. Their research focuses on controlling the dynamics of excited states, including photophysical properties and reactivity, such as energy transfer, charge separation, recombination, and photochemical reactions. This understanding is crucial for applications in solar energy, PCT, and sensing.
Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet, visible (400–750 nm), or infrared radiation (750–2500 nm).

She worked as a professor of chemistry at Hunter College (1980–82), and at Columbia University (1983–89) before joining the California Institute of Technology. In 1997 she became the Arthur and Marian Hanisch Memorial Professor of Chemistry and from 2009 to 2019, the Norman Davidson Leadership Chair of the Division of Chemistry and Chemical Engineering at Caltech. She currently is the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry, Emerita.
Singlet oxygen, systematically named dioxygen(singlet) and dioxidene, is a gaseous inorganic chemical with the formula O=O (also written as 1
[O
2] or 1
O
2), which is in a quantum state where all electrons are spin paired. It is kinetically unstable at ambient temperature, but the rate of decay is slow.
Photosensitizers are light absorbers that alter the course of a photochemical reaction. They usually are catalysts. They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state, where it remains chemically intact, poised to absorb more light. One branch of chemistry which frequently utilizes photosensitizers is polymer chemistry, using photosensitizers in reactions such as photopolymerization, photocrosslinking, and photodegradation. Photosensitizers are also used to generate prolonged excited electronic states in organic molecules with uses in photocatalysis, photon upconversion and photodynamic therapy. Generally, photosensitizers absorb electromagnetic radiation consisting of infrared radiation, visible light radiation, and ultraviolet radiation and transfer absorbed energy into neighboring molecules. This absorption of light is made possible by photosensitizers' large de-localized π-systems, which lowers the energy of HOMO and LUMO orbitals to promote photoexcitation. While many photosensitizers are organic or organometallic compounds, there are also examples of using semiconductor quantum dots as photosensitizers.
