Abstract
The effect of an additional cyano group in A-π-D dyes on optical, electrochemical, and radical polymerization initiating properties was demonstrated using anthracene-containing di- and tricyanoethylenes. It is shown that the transition from the di- to the tricyanoethylene derivative leads to a shift in the reduction potential by 0.47 V to the anodic region, a bathochromic shift of the long-wave absorption band from λmax = 427 nm to λmax = 525 nm in acetonitrile, and also to an increase in the initiation efficiency (maximum rate) of the polymerization of dimethacrylate OKM-2 under the action of LED@405 nm radiation by more than 5 times.
