Moreover, the reactive intermediates are generated under mild conditions, which opens the door to new transformations and to reaction conversions at higher efficiencies. Photocatalysis presents a significant advantage over traditional synthetic methodologies in that it can allow for generation of products which are inaccessible thermally. 1–3 The prospect of the widescale development of greener, more economical reactions that proceed under mild reaction conditions has propelled photocatalysis from a niche concept to a widely accepted and highly useful synthetic strategy. Since 2007, there has been a resurgence of activity in the domain of photocatalysis following the pioneering demonstrations by the likes of MacMillan, Yoon and Stephenson, who showed that photoactive organometallic complexes can mediate useful organic reaction transformations. Introduction In the most basic definition, photocatalysis involves using light as an energy input in concert with a light-absorbing material to increase reaction rates. In 2013, he moved to the University of St Andrews where he is presently Professor of Optoelectronic Materials, Fellow of the RSC and is the holder of a Royal Society Leverhulme Trust Senior Research Fellowship.ġ.

He joined the Université de Sherbrooke as an assistant professor in 2007. Jay Siegel at the University of Zurich and the other in inorganic materials with Prof. He then completed two postdoctoral fellowships, one in supramolecular chemistry with Prof. She is now completing her PhD project at the University of St Andrews and is interested in exploring new photocatalytic reactions with TADF compounds as the photocatalyst.Įli Zysman-Colman obtained his PhD in Chemistry from McGill University in 2003 with Prof. Megan Amy Bryden obtained her MChem from the University of Durham in 2018, with her master's project being undertaken at the Université Grenoble Alpes focusing on luminescent lanthanide redox probes. A discussion of the benefits of compounds showing TADF for photocatalysis is presented, which paints a picture of a very promising future for organic photocatalyst development. Beyond the small number of TADF photocatalysts that have been used to date, the analysis conducted within this review reveals the wider potential of organic donor–acceptor TADF compounds as photocatalysts. This review comprehensively highlights their potential by documenting the diversity of the reactions where an organic TADF photocatalyst can be used in lieu of a noble metal complex photocatalyst. Since 2016, a subset of these have found increasing use as photocatalysts. Organic compounds that show Thermally Activated Delayed Fluorescence (TADF) have become wildly popular as next-generation emitters in organic light emitting diodes (OLEDs).
