Outline of Final Research Achievements

This project aimed at the creation of information and energy transfer system based on the assembly of the multi-nuclear metal complexes through weak intermolecular interactions. A series of cyanide-bridged Co-Fe tetranuclear complexes were prepared and external stimuli-induced magnetic switching were explored. In addition, dimensionally controlled aggregates of the tetranuclear complexes were synthesized using directional hydrogen bonding interactions, in which hierarchical switching of hydrogen bond strengths associated the multi-stepped magnetic phase transitions. On the other hands, a novel tetranuclear platinum complex with extended pai-conjugation was prepared. The platinum complex showed significant enhancement of emission intensity by low-dimensional aggregation bridged by silver ions. The systems described above can be considered as information and energy transfer systems along the low-dimensional integrated structures.
