Metal complexes have structural and electronic flexibilities which respond to external stimulus such as light, heating and guest, leading tothe development of future sensor, memory devices and molecular actuators. Our group are investigating switchable physical properties of spin crossover (spin transition) Fe(II/III) and Co(II) complexes, and coordination polymers responding to the external stimulus.

Soft materials incoporating long alkyl chains show unipue properties such as phase transition and liquid crystalline property based on their structural flexibility. Our group are developing multi-functional soft materials exhibiting structural flexibility yogether with electronic properties by introducing alkyl chains into metal complex cores.

Carbon materials have attravted much attention as the next-generation functional materials. Our group are developing proton conductors based on the carbon materials such as graphene oxide (GO) and carbon sphere (CS). Moreover, we are investigating multi-functions developed by a hybridization of GO with inorganic compounds such as metal oxides and metal complexes.
