| Research Abstract |
The development of new functional molecular materials exhibiting intra molecular electron transfer induced by external-stimuli, such as light and heat, was studied in this research project. As results, we have discovered (i) polymorphs in cobalt di-nuclear complexes, (ii) crystal structure control by synthetic methods, (iii) intra molecular electron transfer behaviors, (iv) multi-bistabilitis in magnetism and dielectricity, (v) new photo-responsive nano-magnets. All these results have been investigated in molecular complexes exhibiting valence tautomerism. The outcomes (i) and (ii) were one of the crystal engineering focusing in crystal growth process and molecular design, respectively. Additionally, the all interesting physical properties listed in (iii)-(v) are due to the well-controlled valence tautomeric behavior, thus, we can conclude that these class of molecules have potentials to be applied next generation functional materials.
