Abstract

The invention discloses a coordination polymer with ferroelectric properties and a preparation method and application thereof. The chemical formula of the coordination polymer is Cd(C17H15N2O2)Cl; at a room temperature, a soluble compound containing Cd<2+> and a phenylalanine derivative are fully mixed and stirred in water, and put into a reaction still, so that the coordination polymer is prepared through self-assembly in a hydrothermal method. The coordination polymer can be applied to manufacturing electrooptic devices, information storage devices, non-linear optic devices and infrared sensors. According to the the coordination polymer with the ferroelectric properties disclosed by the invention, the adoptive materials are simple in preparation process, the operation is easy, the raw material resources are rich, the production cost is low, the productivity is high, and the repeatability is good; the coordination polymer is unlikely to dissolve in ordinary solvent, the thermal decomposition temperature point is relatively high, and the crystal particles are uniform.

Description

technical field [0001] The invention belongs to the technical field of synthesis of molecular-based ferroelectric materials, and in particular relates to a coordination polymer with ferroelectric properties, a preparation method and an application thereof. Background technique [0002] Ferroelectric materials are a class of pyroelectric materials. There is a phenomenon of spontaneous polarization when no external electric field is applied, and within a certain temperature range, the polarization will be reversed or reoriented under the action of an external electric field. Under the action of an external electric field, ferroelectric materials will exhibit hysteresis loop characteristics, such as Xu, Y.H. Ferroelectric materials and their application. New York: Elsevier Science Publisher, 1991. This property of the material is known as "ferroelectricity" or "ferroelectric effect". Due to their excellent ferroelectricity, piezoelectricity, pyroelectricity and nonlinear opti...
