Strong reverse saturable absorption effect of a nonaggregated phthalocyanine-grafted MA–VA polymer

Abstract

The amino-substituted phthalocyanines (<bold>TA-PcInCl</bold>) with high optical limiting effect are grafted onto the copolymer matrix of maleic anhydride (<bold>MA</bold>) and vinyl acetate (<bold>VA</bold>), to obtain a novel phthalocyanine grafted polymer (<bold>MA–VA-PcInCl</bold>) with superior nonlinear absorption effect.
