AI Article Synopsis
- Multicomponent photoinitiating systems have gained attention for designing visible light photoinitiators, but their complexity has led to the development of simpler monocomponent Type II photoinitiators.
- These monocomponent systems merge the photosensitizer and radical/cation generator into a single molecule, making it easier to create photocurable resins.
- Sulfonium salts are effective photoinitiators but traditionally don't absorb visible light, prompting researchers to modify their structures to improve their visibility absorption, which is discussed in this overview.
Article Abstract
During the last decades, multicomponent photoinitiating systems have been the focus of intense research efforts, especially for the design of visible light photoinitiating systems. Although highly reactive three-component and even four-component photoinitiating systems have been designed, the complexity to elaborate such mixtures has incited researchers to design monocomponent Type II photoinitiators. Using this approach, the photosensitizer and the radical/cation generator can be combined within a unique molecule, greatly simplifying the elaboration of the photocurable resins. In this field, sulfonium salts are remarkable photoinitiators but these structures lack absorption in the visible range. Over the years, various structural modifications have been carried out in order to redshift their absorptions in the visible region. In this work, an overview of the different sulfonium salts activable under visible light and reported to date is proposed.
