POLYETHER-KETONE HYPERBRANCHED MOLECULE, AND TRANSITION METAL COMPLEX WITH THE SAME AS LIGAND

摘要

PROBLEM TO BE SOLVED: To provide a transition metal complex having high luminescent ability, chemical stability and solubility to solvent, and to provide a new dendrone to be used therein. SOLUTION: This new dendorone is a polyether-ketone hyperbranched molecule shown by the general formula (1) (A is a focal point functional group selected from the group consisting of carboxy group, ester group and nitrile group; R is a branched end group selected from the group consisting of aryloxy group, alkoxy group and halogen atom; the chemical structure inside the three round brackets a branched structural unit constituting a hyperbranched structure; and the three brackets means that the branched structural units are mutually bound repeatedly). The other objective transition metal complex contains the hyperbranched molecule as the ligand.
