Abstract

The invention discloses a 1-3 generation arylene ether-substituted dendritic phthalocyanine zinc complex, a preparation method and an application thereof. The method comprises the following steps of adopting a Frechet synthesis method to synthesize the first to third generation alcohol molecules which take the 1-3 generation cyan as an end group; leading the first to third generation alcohols to react with 4-nitrophthalonitrile respectively, thus synthesizing corresponding phthalocyanine precursor of dendrimer taking the 1-3 generation cyan as the end group; subsequently, leading the phthalocyanine precursor ring of dendrimer taking the 1-3 generation cyan as the end group to synthesize corresponding arylene ether dendritic phthalocyanine taking the first to third generation cyan as the end group and the arylene ether dendritic phthalocyanine taking the first to third generation carboxyl as the end group generated by hydrolysis. The 1-3 generation arylene ether dendritic phthalocyaninecomplex and the amphiphilic block copolymer are automatically dissolved to form the polymer nano-particle loading the 1-3 generation arylene ether dendritic phthalocyanine complex. The 1-3 generation diaryl ether dendritic phthalocyanine zinc complex and the loaded polymer nano-particle thereof are used as photosencitizers for photodynamic therapy.

Description

Technical field: [0001] The invention belongs to the field of complexes, in particular to a 1-3 generation aryl ether dendritic zinc phthalocyanine complex and its polymer nanoparticles and a preparation method thereof. The complex is used as a photosensitizer for photodynamic treatment of wet macular degeneration diseases And cancer. Background technique: [0002] Photodynamic therapy (PDT) is a new method to treat cancer, HIV and wet macular degeneration. The key to photodynamic therapy is photosensitizer. Since the phthalocyanine complex has a skeleton structure similar to that of hematoporphyrin, the structure is more stable and easy to modify. The maximum absorption wavelength is about 670nm. It can easily penetrate the red light region of human tissues and can be made into pure products. It is considered a class Very potential photosensitizer. Due to the strong π-π interaction between the phthalocyanine molecules, it is easy to aggregate, thereby reducing the fluorescenc...
