Abstract

The invention discloses a fluoro aryl benzyl ether dendritic (phthalocyanino) silicon complex as well as a preparation method and applications thereof. The preparation method comprises the following steps: firstly, synthetizing dichloro (phthalocyanino) silicon; then, in the presence of potassium carbonate, reacting p(nitro or cyano, ester, benzophenone) benzyl bromide with 2,2-bi(4-hydroxyphenyl) hexafluoropropane so as to synthetize 2-(4-hydroxyphenyl)-2'-(4-(4-nitro or cyano or ester or benzophenone-benzyloxy); finally, respectively carrying out reflux reaction on dichloro(phthalocyanino) silicon and 2-(4-hydroxyphenyl)-2'-(4-(4-nitro or cyano or ester or benzophenone-benzyloxy) hexafluoropropane in methylbenzene so as to synthetize di-(2-(4-phenoxy)-2'-(4-(4-nitro or cyano or ester or benzophenone-benzyloxy)hexafluoropropane) for axially replacing a silicon (IV) phthalocyanine complex. In such a way, a fluoro dendritic ligand modified phthalocyanine complex becomes a photosensitizer with good photodynamic therapy potential.

Description

technical field [0001] The invention belongs to the field of complexes, in particular to a fluorinated aryl benzyl ether dendritic phthalocyanine silicon complex and its preparation method and application. The complex is used as a photosensitizer for photodynamic treatment of wet macular degeneration diseases and cancers and cell imaging. Background technique [0002] Photodynamic therapy (PDT) is a new approach to treat cancer, HIV and wet macular degeneration-like diseases. The key to photodynamic therapy is the photosensitizer. Phthalocyanine complexes have a similar skeleton structure to hematoporphyrin, are more stable and easy to modify, and have a maximum absorption wavelength of around 670nm. They are easy to pass through the red light region of human tissues and can be made into pure products. Potential photosensitizer. Due to the strong π-π interaction between phthalocyanine molecules, it is easy to aggregate, thereby reducing the fluorescence quantum yield of p...
