Shining a light on an adaptable photoinitiator: advances in photopolymerizations initiated by thioxanthones
TL;DR: A review of the photochemistry of thioxanthone-based systems and their use in different modes of photo-initiated polymerizations is presented in this paper, where the development of various photoinitiating systems along with an understanding of their mechanistic behavior has been elucidated previously.
