Abstract
During the last three decades, the fields of photopolymerization and photoimaging science and technology have developed from a rather specific topic into one of great industrial importance [Citation1–5]. This topic is now of central importance in polymer science and technology. Inherent in these technologies is the use of photo-activator systems, which are capable of absorbing the incident UV and/or visible radiation wavelength used for converting a monomer or pre-polymer system into a crosslinked network. In recent years, there have been new developments in the synthesis and photochemical studies of novel photoinitiator molecules.
