Outline of Final Research Achievements

Unique metal coordination asymmetry on solid surfaces were prepared by metal-complex attachment and surface functionalization techniques. By the collaborative works in the research unit, the attachment and functionalization of Co3 cluster, V complex, Tb complex were achieved on SiO2 surfaces and new asymmetric coordination structures were prepared at the surfaces. We characterized the prepared asymmetric coordination structures by XAFS, CD, CPL, theoretical calculation etc. and their unique reaction performances were investigated.
