Abstract

The present invention provides a method for regulation and control of morphology of an amino acid / rare earth coordination polymer by using a surfactant. Since the surfactant with different charges has different ways of adsorption or coordination with rare earth ions or amino acids, so as to achieve the change of the morphology of the amino acid / rare earth coordination polymer from a drum shape under the surfactant-free conduction to a pie shape, dumbbell shape and prismatic drum under hydrothermal conditions. The method has the advantages of simple operation, inexpensive surfactant and obvious regulation and control effect on the morphology of the rare earth coordination polymer.

Description

technical field [0001] The invention relates to a method for controllably adjusting the morphology of rare earth coordination polymers, in particular to a method for regulating the morphology of amino acid / rare earth coordination polymers by using surfactants with different charge types, and belongs to the field of rare earth luminescent material preparation. Background technique [0002] Coordination polymers are bridged by metal ions and organic ligand molecules through chemical coordination. Like traditional rare earth complexes, rare earth coordination polymers also have the unique fluorescence properties of rare earth ions, such as high luminous efficiency, large Stokes shift, long fluorescence lifetime and anti-photobleaching. It has great application prospects in phase catalysis, optics, magnetism and so on. [0003] Biomolecules are widely used in the preparation of coordination polymers due to their good biocompatibility and low price. Among the reported biomolecu...
