Abstract

The invention relates to a 1,2-naphthalene diacid containing cadmium coordination complex and a preparation method thereof. The coordination complex has the following chemical formula: [CdL(bpe)(H2O)]infinity, wherein L is equal to a 1,2-naphthalene diacid carboxylic anion ligand; and bpe is equal to 1,2-bis(4-pyridyl)ethane. The synthesis method of the coordination complex is characterized by dissolving a 1,2-naphthalene diacid anhydride ligand, 1,2-bis(4-pyridyl)ethane and metal cadmium salt into water under the hydrothermal condition to prepare solution, sealing the solution into a 25mL reaction kettle, heating the solution to a certain temperature at a rate of 10 DEG C per hour, maintaining the temperature for three days and then naturally reducing the temperature to the room temperature, thus obtaining the coordination complex. The obtained crystalline material is expected to be further researched, developed and applied in the field of fluorescent materials.

Description

technical field [0001] The present invention relates to d 10 The field of metal complex fluorescent materials, especially a cadmium 1,2-naphthalate complex and its preparation method. The complex has a two-dimensional (6,3) topological network structure and can be used as a fluorescent material be further developed and applied. Background technique [0002] At present, the research on various organo-metal coordination polymer materials formed by coordination self-assembly or controllable assembly of pre-designed organic ligands and metal ions is very active and showing a trend of in-depth development. The research results have been widely reported in top journals such as Science, Nature, JACS, Angew, etc. In particular, the research on the construction and internal structure-activity relationship of metal complexes (Metal Coordination Complex) with special surface and interface properties (such as light, electricity, magnetism, adsorption separation, catalysis, biological ...
