“…[16][17][18][19][20] However, one of the main obstacles for photopolymerization used in 3D printing is that existing photoinitiators are not fully adapted to the current irradiation wavelength at 405 nm. [21][22][23][24][25] The research on the combination of iodonium salts and amines as versatile initiating systems for photochemical application has been recently reported by our group. [26,27] In the present paper, the active photoinitiating systems will be composed by three specific components: heterocyclic group-substituted ketones, amine and iodonium salt.…”

2-Naphthyl)-2-(1-pyrrolidinyl)ethanone (MPY) was synthesized as a photoinitiator for free radical polymerization and the structure was characterized by spectral analysis. MPY has ability to initiate the polymerization of methyl methacrylate (MMA) monomer in air upon irradiation. Absorption and fluorescence properties of this initiator are investigated and the singlet excited-state energy value calculated in dichloromethane. According to the results, MPY acts as a type 2 photoinitiator.

“…The proposed mechanism of the photoinitiation relies on the photoexcitation of TX-A photoinitiator and quenching the triplet excited state primarily by molecular oxygen to form singlet oxygen species. [125][126][127] Carbazole functionalities were also taken advantage of forming one-component TX photoinitiators with extended conjugation. The endoperoxide thus formed undergoes photochemical or thermal decomposition resulting in the formation of initiating radicals.…”

Photochemistry has been playing a central role in the synthetic polymer community. Aromatic ketones, examples of which include benzophenone, thioxanthone, camphorquinone, among others, are renowned for their excellent optical characteristics and have been extensively taken advantage of photochemically induction of polymerization processes. Of particular interest is thioxanthone due to its adaptability for bearing different functionalities and applications in various modes of photopolymerization which accomplishes photoinitiation in conjunction with other co-initiator compounds; a behavior that is referred to as bi-molecular photoinitiation. In this paper, we review the photochemistry of thioxanthonebased systems and their use in different modes of photoinitiated polymerizations. Citing examples from literature, the development of various photoinitiating systems based on thioxanthones along with an understanding of their mechanistic behavior has been elucidated in advance.Scheme 1 Typical representation of the photolysis of the radical photoinitiators based on Type I (top) and Type II (bottom) systems on the example of a benzoin derivative and thioxanthone, respectively.Scheme 3 Synthesis of thioxanthones by condensation of thiosalicylic acid and aromatic compounds in the presence of concentrated sulfuric acid.
