WebJul 19, 2024 · The photochemical deracemization of 2,4-disubstituted 2,3-butadienamides (allene amides) was investigated both experimentally and theoretically. The reaction was catalyzed by a thioxanthone which is covalently linked to a chiral 1,5,7-trimethyl-3-azabicyclo[3.3.1]nonan-2-one skeleton providing a U-shaped arrangement of the … WebJul 13, 2024 · 1 INTRODUCTION. Thioxanthone 1 is a popular triplet sensitizer in photoinitiated reactions because of its high molar absorptivity in the near-UV spectral region (300-400 nm), high triplet quantum yield and relatively high triplet energy. 1, 2 Thioxanthone and its derivatives are frequently used in organo-photocatalytic reactions 3, 4 and as … WebSep 2, 2024 · Time Dependent Density Functional Theory has been used to assist the design and synthesis of a series thioxanthone triplet sensitizers. Calculated energies of the triplet excited state (E T) informed both the type and position of auxochromes placed on the thioxanthone core, enabling fine-tuning of the UV-vis absorptions and associated triplet … fisher price cash register set
