Abstract
Investigation of functional solid materials is an important topic in the field of chemistry and materials science. Our laboratory has paid attention to cyanido-bridged metal assemblies and nano-sized metal oxide systems. Cyanido-bridged assemblies are suitable systems to control electronic and magnetic state by external stimuli and observed humidity sensitive magnetism, interference effect between magnetic ordering and ionic conductivity, photo-induced magnetization due to charge transfer induced spin transition and spin-crossover phenomenon, and nonlinear magneto-optical effect, chiral photo-switching magnet exhibiting orthogonal switching of polarization of second harmonic light by photo irradation, etc. Furthermore, by utilizing nano-scale chemical synthesis, we have realized huge coercive field, electromagnetic wave absorption, room temperature photo-induced phase transition, and thermal energy storage in nano-sized metal oxides from abundant elements such as iron or titanium. In this presentation, I will introduce syntheses, functionalities, and mechanisms of some of these functional cyanido-bridged metal assemblies and metal oxide nano materials based on rational design and strategies.
