The syntheses of several phenothiazine compounds bearing cationically polymerizable vinyl, vinyl ether and epoxide groups are described. These monomers were rapidly and efficiently polymerized or copolymerized by UV irradiation in the presence of onium salt photoinitiators. In addition, the monomers simultaneously function as efficient photosensitizers for the photolysis of the onium salts. In this article, the use of these ...
