Multifunctional Materials Combining Spin-Crossover with Conductivity and Magnetic Ordering

This chapter introduces compounds synthesized to develop new spin-crossover conductors, in which spin-crossover phenomena and conductivity coexist or interact. It also introduces spin-crossover magnets, in which spin-crossover phenomena and magnetic interaction coexist or interact. A possible route for the synthesis of multifunctional materials exhibiting spin-crossover and conductivity is the preparation of double salts, by combining spin-crossover cations/anions and conducting molecular anions/cations through electrostatic interactions. Another route is the preparation of a spin-crossover complex with a potentially conducting ligand. The preparation of spin-crossover conductors in which conductivity and light-induced excited spin state trapping (LIESST) exhibit synergistic effects is desired. Multifunctional materials exhibiting both spin-crossover and magnetic interaction are achieved by combining a spin-crossover cation/anion with an anionic/cationic magnetic framework. Another route is the incorporation of spin-crossover sites into magnetic frameworks. This edition first published 2013
