Trends in Dye Photosensitized Radical Polymerization Reactions

In this chapter, visible light-induced radical polymerization reactions in the 380-800 nm range are reviewed. The role of the absorbing species (dye) and the complete multicomponent photoinitiating systems (PISs) (dye and additives) are then emphasized. The original works on the dye-based PISs that have been proposed over the years are also outlined. However, this chapter is mainly focused on the latest developments, in the 2010-2014 period, and the actual trends of research, in particular the novel perspectives of applications under soft irradiation conditions. 

Dye photosensitized polymerization (DPP) (see [FOU 12a]) is a common expression often employed [OST 54, EAT 86, MON 93] to refer to a series of reactions where a dye (i) is excited by light [l.la], (ii) leads [1.1b], alone or through primary or subsequent reactions involving one or more

2 Dye stands for the first excited singlet state of the dye and is formed under excitation by light Dye is the triplet state of the dye generated from Dye through an intersystem crossing.
