Abstract

The invention relates to a zinc phthalocyanine derivative and a preparation method thereof. The chemical formula of the derivative is C56H52N12O8Zn. In the method, a pyrimidine oxy group with a long alcoxyl chain is introduced at the periphery of a large ring of zinc phthalocyanine, so that the amphipathy and the biocompatibility of the zinc phthalocyanine are improved, and the photodynamic activity is improved. The zinc phthalocyanine derivative is difficult to gather, so the improvement on the cellular uptake rate is facilitated, and the photodynamic activity is improved; the derivative has a single compound structure, an isomer does not exist, and the product can be purified easily; and the synthetic method is simpler, higher in yield and low in cost, and is favorable for industrialized production, few side reactions are performed, and raw materials are readily available.
