INTERNALLY ENCAPSULATING AGENT HAVING INNER SPACE AND COMPOSED OF METAL COMPLEX

摘要

PROBLEM TO BE SOLVED: To obtain an internally encapsulating agent comprising three- dimensional cage-like transition metal complex capable of selectively encapsulating a chemical substance by the size of the interior of the three dimensional structure, polarity, various kinds of affinity, or the like. SOLUTION: This internally encapsulating agent is a chemical substance comprising a three-dimensional cage-like transition metal complex which has a space inside. The ligand of the three-dimensional cage-like transition metal complex substantially has a plane structure, and is the compound having three or more electronic pairs capable of forming coordination bonds with the transition metal in the molecule.
