Abstract

The invention discloses a preparation method of a carboxybenzaldehyde 1,3-propane diamine Schiff base copper complex. The method comprises the following steps: by using carboxybenzaldehyde and ethylenediamine as raw materials, glacial acetic acid as a catalyst and absolute methanol as a solvent, carboxybenzaldehyde 1,3-propane diamine Schiff base is prepared through a solution method; by using thecarboxybenzaldehyde 1,3-propane diamine Schiff base, and copper acetate monohydrate as raw materials, and the absolute methanol as a solvent, the carboxybenzaldehyde 1,3-propane diamine Schiff base copper complex is prepared through a hydrothermal method. The method disclosed by the invention has the advantages of simple process, good reproducibility and higher yield; the prepared carboxybenzaldehyde 1,3-propane diamine Schiff base and the carboxybenzaldehyde 1,3-propane diamine Schiff base copper complex both have fluorescence properties, and have potential application values in the fields of fluorescent probes and fluorescence analysis.

Description

technical field [0001] The invention relates to a bis-Schiff base, in particular to a preparation method of an o-carboxybenzaldehyde acetal 1,3-propanediamine Schiff base copper complex. Background technique [0002] Schiff base is a class of compounds containing imine (-CH=N-) or amethymine (-CR=N-) groups produced by the condensation reaction of two types of substances containing primary amino groups and active carbonyl groups. There are different types of Schiff bases according to different classification methods. According to the structural formula, they can be divided into single Schiff bases, double Schiff bases, macrocyclic Schiff bases, heterocyclic Schiff bases, etc.; according to the group coordination mode It can be divided into amines, ketals, etc.; it can be divided into mononuclear, multinuclear, etc. according to the different coordination metals. Since the Schiff base molecule contains a C=N bond, it not only contains an unsaturated double bond, but the nitr...
