The results that demonstrate that methoxynapthyl-substituted 1-(Arylmethyloxy)anthracenes derivative (1d) is a good candidate for the practical hybrid type photoinitiator consisting of only carbon, hydrogen, and oxygen atoms. The event to which absorbance at 390 nm is decreased per second was found to be lowered, suggesting some contribution of charge transfer type interaction between the two aromatic chromophores in the excited state to the overall photoreactivity. Analysis of the 1d-derived product distribution indicated that arylmethyloxyl radical and the arylmethyl carbonium ion were initiating species for the radical and cationic polymerization reactions of the given monomers. It was concluded that the arylmethyloxyl radical and the arylmethyl carbonium ion are involved as reactive intermediates to initiate the polymerization of St and cyclohexane oxide (CHO).
