Over the past several decades, photopolymerization has become an active research field, and the ongoing efforts to develop new photoinitiating systems are supported by the different applications in which this polymerization technique is involved—including dentistry, 3D and 4D printing, adhesives, and laser writing. In the search for new structures, bis-chalcones that combine two chalcones’ moieties within a unique structure were determined as being promising photosensitizers to initiate both the free-radical polymerization of acrylates and the cationic polymerization of epoxides. In this review, an overview of the different bis-chalcones reported to date is provided. Parallel to the mechanistic investigations aiming at elucidating the polymerization mechanisms, bis-chalcones-based photoinitiating systems were used for different applications, which are detailed in this review.

Highly Efficient

New 2-(diethylamino)-4,6-diphenyl-benzene-1,3-dicarbonitrile derivatives were proposed as photoinitiators in conjunction with iodonium salts for: (i) the cationic polymerization, (ii) the free-radical polymerization, and (iii) the synthesis of IPNs.
