Abstract

Abstract : A series of thioxanthone dicarboxamide derivatives containing hydrogen donors as one-component LED photoinitiators have been prepared. Abstract : A series of thioxanthone dicarboxamide derivatives (TX-DCAs) containing hydrogen donors as one-component photoinitiators (PIs) have been prepared. In particular, the photoreactivity of these PIs was remarkably improved due to the covalent binding of the N -phthalimido derivative and type II chromophore thioxanthone. These derivatives exhibit interesting shifted absorption so that they can be utilized as versatile PIs upon exposure to various violet and visible LEDs (365 nm, 385 nm, 395 nm and 405 nm), and can efficiently actuate the free radical photopolymerization of acrylates.
