5-Thia-naphthacen-12-one (TX-Np) was synthesized as a potential photoinitiator for radical polymerization. Polymerization studies revealed that TX-Np acts as a photoinitiator for radical polymerization of acrylic type monomers in the presence of N-methyldiethanolamine (MDEA). The phosphorescence spectrum measured at 77 K in ethanol showed an emission band at lambda (max) = 505 nm corresponding to the approximate triplet energy of ca. 237 kj/mol.
