Molecule-based magnets are widely recognized as excellent materials from the viewpoints of flexible designability, controllable magneto-elastic coupling, optical transparency, processability, and multifunctional possibilities compared to inorganic magnets. Due to these advantages, molecule-based magnets are considered essential for future innovation. There are several types of molecule-based magnets: 1) Prussian blue type magnets, 2) spin crossover type magnets, 3) low-dimensional magnets, 4) single-molecule and single-chain magnets, 5) other bifunctional magnets, 6) pure organic magnets, 7) conventional metal-complexes-based magnets, 8) porous magnets, and 9) others. In this symposium, we will focus on "Functional Molecule-Based Magnets" with electrical conductivity, ferroelectrics, chirality, interesting optical properties, photo-induced phase transitions, nonlinear optical properties, gigantic magneto resistance (GMR), field effect transistor (FET) systems, Haldane gap systems, etc. We will discuss the achievements of the research involving these materials as well as the perspectives of Functional Molecule-Based Magnets. |
