Diisopropyl propylamine tetrafluoroborate crystal material as well as preparation method and application thereof

Abstract

The invention discloses a diisopropyl propylamine tetrafluoroborate crystal material as well as a preparation method and application thereof, and belongs to the field of organic and inorganic hybrid materials. The crystal material is crystallized in a Pna21 ferroelectric space group at room temperature and has two times of reversible phase change near 323.5K and 404K, and the heat absorption capacities measured by differential calorimetric scanning are 40.375 J / g and 11.014 J / g respectively. In addition, the crystal structure is simple in preparation process, has good thermal stability and hydrophilic and oleophylic properties, can be produced on a large scale, and can be used as an amphiphilic room-temperature ferroelectric material with low cost and a clear structure.

Description

technical field

[0001] The invention belongs to the field of organic-inorganic hybrid materials. More specifically, it relates to the organic synthesis of diisopropylpropylamine, the preparation of diisopropylpropylamine tetrafluoroborate, its crystal structure, and its application. Background technique

[0002] Ferroelectric materials are an important class of electronic functional materials with wide application and good performance. Because of their ferroelectric switching effect, pyroelectric effect, photocurrent effect, piezoelectric effect, acousto-optic effect, Refractive effect and other characteristics, so it can be used to develop non-volatile ferroelectric memory, ferroelectric optical memory, infrared detector, optical waveguide device, spatial light modulator, capacitor, surface acoustic wave device, micro drive and laser frequency doubler, etc. functional devices. Ferroelectric materials have spontaneous polarization, and the spontaneous polarization has two ...
