Abstract

The invention relates to a pyridine-containing TTF (tetrathiafulvalene) derivative and a preparation method thereof. The pyridine-containing TTF derivative is applied to the research on organic conductors and organic superconductors.

Description

technical field [0001] The present application relates to a pyridine-containing TTF (tetrathiafulvalene) derivative and a preparation method thereof. Background technique [0002] The construction of new molecular functional materials with multiple physical properties that interact and synergize is currently a research hotspot in the field of chemistry and materials science in the world, and it is also one of the most challenging research fields. For a long period of time, the scientific community believed that superconductivity and magnetism were two contradictory properties, because the Cooper pair would be collapsed by the external or internal magnetic field generated by the ferromagnet. Therefore, realizing superconductivity in a system with a local magnetic moment is an important theoretical research object. With the development of scientific research, especially the development of research on organic conductors and superconductors, scientists have discovered that due ...
