Recent advances on carbazole-based oxime esters as photoinitiators of polymerization

Recent advances on benzylidene cyclopentanones as visible light photoinitiators of polymerization

“…Besides, there are still rooms for improvements. Notably, at present, no type I photoinitiators have been designed with benzylidene cyclopentanones such as oxime esters [102,107,230,232,235,236,[397][398][399][400][401] or glyoxylates for one photon polymerization. [402][403][404][405] Besides, it could greatly help to simplify the composition of the photocurable resins.…”

Recent advances on photobleachable visible light photoinitiators of polymerization

“…[98] Since a couple of years, Type I photoinitiators that are monocomponent systems are about to become more studied than Type II photoinitiators. [188,[206][207][208][209][210][211][212][213] Indeed, Type I photoinitiators contribute to simplify the composition of the photocurable resins. Among all Type I photoinitiators, oxime esters are widely studied due to their easiness of synthesis and their low cost.…”

“…[238] Indeed, phenothiazine is a wellknown electron donor that was used for the design of numerous photoinitiators due to the easiness of chemical modifications. [238][239][240][241][242][243][244][245][246][247][248] A similar easiness of chemical modifications can also be mentioned for carbazole [152,206,207,[249][250][251][252][253][254][255][256][257][258][259] and triphenylamine [260,261], but also for other popular scaffolds for the design of photoinitiators such as naphthalimide, [97,227,228,[262][263][264][265][266][267][268][269][270][271][272][273][274][275][276]…”

Recent advances on benzylidene ketones as photoinitiators of polymerization

“…In 2019, Tao Wang and coworkers reported two benzylidene ketones bearing two peripheral groups extensively used in photopolymerization, namely triphenylamine [226] and carbazole. [149,155] TPAK and CZK were notably used to initiate the free radical polymerization of tripropylene glycol diacrylate (TPGDA) using triethanolamine (TEOA) as co-initiator (See Figure 8). [205] Noticeably, the two dyes exhibited interesting photobleaching properties upon irradiation at 460 and 520 nm and the polymerization of ceramic suspensions could even be realized.…”
