Recent advances on Anthraquinone-based photoinitiators of polymerization

The design of photoinitiating systems activable in the visible range and under low light intensity is an active research field supported by the vast applications of photopolymerization. In the search for new dyes that can exhibit panchromatic absorptions, anthraquinone has been identified as a promising scaffold. Over the years, numerous modifications have been carried out on this scaffold by molecular engineering, enabling to design water-soluble, panchromatic or photobleachable dyes. In this review, an overview of the recent advances concerning photopolymerization with anthraquinone-based photoinitiating systems is given.
