Problems solved by technology

As a fluorescent probe used in the field of medicine, it also needs to have the characteristics of hydrophilicity, low aggregation, high stability and easy synthesis. However, there are still few reports on phthalocyanine complexes with high fluorescence quantum yields with the above characteristics.

Abstract

The invention discloses several non-peripherial substituted phthalocyanine metal complexes and making method, which introduces functional group into position a (position 1(4), 8(11), 15(18) and 22(25)) of phthalocyanine complex.

Description

technical field [0001] The invention belongs to the field of organic functional materials (including medical materials), and specifically relates to a non-peripheral substituted phthalocyanine metal complex and a preparation method thereof. Background technique [0002] Phthalocyanine complexes are an important class of functional materials, which have been widely used in textile, printing and many other high-tech fields. Phthalocyanine metal complexes are also used as photosensitizers in photodynamic therapy (or diagnosis or purification or disinfection), or as fluorescent probes in biosensors. [0003] However, the currently reported biologically active phthalocyanine complexes still have deficiencies, such as lack of water solubility, poor stability, or complex synthetic routes, which need further improvement. Most planar substituted phthalocyanine photosensitizers are highly aggregated in physiological systems, resulting in a significant decrease in their fluorescence q...
