Abstract

The invention discloses a proton-regulated spin-crossover complex and a preparation method and application thereof. The proton-regulated spin-crossover complex consists of a mononuclear ferrous compound [Fe( H2Bpz2 )2( bipy-NH2 )] containing amino functional groups and an inorganic monoacid, the chemical structural formula is as follows: (img file=DDA0001073756450000011.TIF wi=496 he=334 / ), wherein A is Cl, Br, I, NO<3>, BF<4>, ClO<4>, PF<6> and SbF<6>. The spin-crossover complex disclosed by the invention realizes a proton-regulated spin-crossover behavior within a normal temperature range under the effect of different inorganic monoacids. The proton-regulated spin-crossover complex is easy to synthesis, is high in yield, has sable properties, and has an enormous application prospect in terms of information storage and molecular electronic devices such as molecular switches and molecular display.

Description

technical field [0001] The invention belongs to the field of spin cross-complex materials, and more specifically relates to a proton-regulated spin cross-complex and its preparation method and application. Background technique [0002] In the information age, the research and development of electronic devices based on molecular-based materials continues to attract a lot of attention. Designing and synthesizing molecular-based materials with specific structures and functions has become one of the current research hotspots in chemistry, physics and materials science. Among the many molecular-based materials, molecular-based magnetic materials are due to their structural diversity, ease of modification, controllability of structure-activity relationship, adjustable magnetic properties, ease of processing, and ease of integration with other properties (mechanical, optical, electrical, etc.) etc.) combined with other properties make them widely used in quantum computers, high-den...
