Description

In this paper, seven new photoinitiators based on the benzophenone scaffold are specifically designed for photopolymerization under mild conditions upon light-emitting diode (LED) irradiation, i.e. four benzophenone-triphenylamine photoinitiators (denoted as BT1-BT4) and three benzophenone-carbazole photoinitiators (denoted as BC1-BC3). Noticeably, these structures have never been reported in the literature except for BT4, so these molecules have been specifically designed for...[Show more]
