CERIUM COMPLEX AND ORGANIC ELECTRONIC ELEMENT CONTAINING THE CERIUM COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide a cerium complex excellent in electron acceptability and hole acceptability.;SOLUTION: The cerium complex is expressed by composition formula (1). In the formula, M represents a cerium ion; A represents a carbon atom, silicon atom, nitrogen atom, nitrogen cation, boron anion, phosphorus atom, or P(=O); when z is 4, m is 1 to 4 and when z is 3, m is 1 to 3; D represents a direct bond or a hydrocarbondiyl group; G represents a heterocyclyl group or a hydrogen atom; L represents a group that contains an aromatic six-membered ring having two or more nitrogen atoms; X represents a counter ion; L' represents a monodentate or bidentate ligand; a represents a number of 1 to 4; b represents a number of 0 to 5; and c represents a number of 0 to 5.;COPYRIGHT: (C)2013,JPO&INPIT
