“…[4] DLP 3D printing, involving layer-by-layer rapid photopolymerization of photosensitive liquid resin to solid polymer, makes use of the outstanding features of photopolymerization, such as cure on-demand with spatial control of the curing process and energy savings and therefore has attracted much public attention in recent years . [5][6][7] Many applications have been developed with a wide range of uses, such as, for example, personalized consumables, dental materials, food production, biomaterials, and tissue engineering. [1,[8][9][10][11] In photochemical based 3D printing, the photosensitive system mainly consists of monomers, oligomers and photoinitiators.…”

The development of novel visible light photoinitiators (PIs) with low mobility for 3D printing will open up new applications for photopolymerization. In this work, a polymerizable visible light PI DCCA containing an oxime acryloyl ester structure was designed and synthesized. Its linear absorption has a maximum in the visible region (400-480 nm), overlapping well with the emission spectra of conventional blue light sources, and it can effectively induce acrylate polymerization under irradiation with a 450 nm LED lamp. In addition, migration of DCCA in the 3D printed samples is very low compared with DCCB, which has a similar structure but a phenyl moiety instead of the copolymerizable acrylate as the oxime ester group. The utility of DCCA in 3D printing was demonstrated by printing a 3D object with challenging geometric features with high resolution and accuracy.

“…Concomitant to the development of visible light photoinitiating systems, cheap, compact and lightweight irradiation setups have been developed such as the Light-emitting Diodes (LEDs) or the Laser diodes making the traditional irradiation systems obsolete. Over the years and in order their absorption spectra to perfectly fit with the emission spectra of the different visible light sources, a wide range of structures have been examined as visible light photoinitiators such as acridones 1, [18,19] acridine-1,8-dione 2, [20,21] benzophenones 3, [22][23][24][25] camphorquinones 4, [26,27] carbazoles 5, [28][29][30][31][32][33] chalcones 6, [34,35] chromones 7, [36][37][38] coumarins 8, [39][40][41][42][43] copper complexes 9, [44][45][46][47][48][49][50][51][52][53][54] cyclohexanones 10, [55][56][57] dihydroanthraquinone 11, [58] 2,3-diphenylquinoxaline derivatives 12, [59] diketopyrrolopyrrole 13, [60]…”

Photoinitiators of polymerization that can be activated under visible light and low intensity are actively researched as these compounds constitute the next generation of photoinitiators that will replace the controverted UV-photoinitiators. Over the years, a family of compounds has been identified as being highly promising in light of its remarkable photoinitiating ability, photochemical stability, low cost and easiness to functionalize, namely carbazoles. In this review, an overview of the different carbazole-based photoinitiators reported to date is presented. Interestingly, carbazoles have mostly been used as electron donors in push-pull structures, as photosensitizers for iodonium salts, as ligands for ferrocenium salts or as chromophores for phenacyl onium salts. These different applications clearly demonstrate the versatility of this structure used as the elemental building block for the design of UV, near-UV or visible light photoinitiators.
