Long wavelength photosensitizers in photoinitiated cationic polymerization: The effect of quinoxaline derivatives on photopolymerization

In silico rational design by molecular modeling of new ketones as photoinitiators in three-component photoinitiating systems: application in 3D printing

“…[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.…”

Recent Developments of Versatile Photoinitiating Systems for Cationic Ring Opening Polymerization Operating at Any Wavelengths and under Low Light Intensity Sources

“…Original and different cationic skeletons include dialkyl and cycloalkyl sulfonium salts, phenylethynyl sulfonium salts, acylsulfonium salts, dialkyl aryl sulfonium salts, thianthrenium salts or onium salts centered on a N (e.g., quinolinium, ammonium, anilinium salts, P (pyridinium, phosphonium salts), O (pyrilium salts) or a S atom (thiopyrilium, thiazolinium salts). Interesting results can be found in e.g., [ 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 ].…”

Visible light sensitive photoinitiating systems: Recent progress in cationic and radical photopolymerization reactions under soft conditions

“…Several attempts have also been made for the cationic PISs under long wavelength UV lights (>300 nm) [73][74][75][76][77][78][79][80][81][82][83] or even visible lights [84][85][86][87][88][89][90][91][92][93][94]. However, photopolymerization reactions under low intensity visible light irradiation conditions were rather rare and challenging before 2011.…”
