A bifunctional benzophenone-carbazole-based photoinitiator (BPC) was designed from its molecular structure viewpoint. To achieve this, two benzoyl substituents were introduced as peripheral groups of carbazole, so that a molecule in which two benzophenones were fused to one carbazole unit could be obtained in a one-step procedure. As a result of this combination, synergetic effects are thus achieved. Interestingly, BPC could efficiently initiate the free radical photopolymerization (FRP) of...[Show more]
