Graphene oxide covalently functionalized with zinc phthalocyanine for broadband optical limiting (2011)

Abstract A soluble graphene oxide (GO) covalently functionalized with zinc phthalocyanine (PcZn), GO-PcZn, was synthesized by an amidation reaction. The formation of an amido bond between PcZn and GO has been confirmed by x-ray photoelectron and Fourier transform infrared spectroscopy. At the same level of linear extinction coefficient, GO-PcZn exhibited much larger nonlinear optcial extinction coefficients and broadband optical limiting performance than GO at both 532 and 1064 nm, indicating a remarkable accumulation effect as a result of the covalent link between GO and PcZn.
