“…Carbazole compounds are also efficient electron-transfer photosensitizers for a wide variety of onium salt photoinitiated cationic polymerizations, and polymers containing carbazole compounds are generally very good photosensitizers. Crivello et al, found that the inclusion of even a small amount of a carbazole photosensitizer, such as PVK, was effective in markedly accelerating the photopolymerizations of epoxide and vinyl ether monomers [14,15]. The broadening of the spectral response through the use of these carbazole-based photosensitizers accounted for the rate enhancement of the polymerization reactions.…”

“…The carbazole structure is very interesting in photopolymerization. Some derivatives were used as additives to boost the photopolymerization reaction (radical and cationic processes) [14]. More recently, other carbazole derivatives have been used as photoinitiators for LED polymerization [15] and showed that their good reactivity was mostly due to their high absorbance around 400 nm in two-component systems.…”

Carbazole structures are of high interest in photopolymerization due to their enhanced light absorption properties in the near-UV or even visible ranges. Therefore, type I photoinitiators combining the carbazole chromophore to the well-established phosphine-oxides were proposed and studied in this article. The aim of this article was to propose type I photoinitiators that can be more reactive than benchmark phosphine oxides, which are among the more reactive type I photoinitiators for a UV or near-UV light emitting diodes (LED) irradiation. Two molecules were synthesized and their UV-visible light absorption properties as well as the quantum yields of photolysis and photopolymerization performances were measured. Remarkably, the associated absorption was enhanced in the 350–410 nm range compared to benchmark phosphine oxides, and one compound was found to be more reactive in photopolymerization than the commercial photoinitiator TPO-L for an irradiation at 395 nm.

“…Another way is to polymerize these monomeric photosensitizers and afterwards subject them to sensitize the polymerization of convenient monomers. In both ways non-toxic and odorless polymers can be obtained after polymerization [201][202][203][204].…”
