Abstract
A luminescence device is principally constituted by a pair of electrodes and an organic compound layer disposed therebetween. The organic compound layer contains a metal coordination compound characterized by having a partial structure represented by the following formula (1): wherein each of N and C represents an atom constituting a cyclic group.
Claims1
A luminescence device comprising a pair of electrodes, a luminescence layer disposed between the electrodes and an organic layer, which is disposed between the electrodes and is different from the luminescent layer, the luminescent layer comprising a metal coordination compound represented by formula (4):
- wherein:
- (i) the compound of formula (4) is optionally and independently substituted with at least one C1-C20 alkyl group, C1-C20 alkoxy group or a trimethylsilyl group, which said alkyl, alkoxy and trimethylsilyl groups are optionally substituted with a fluorine;
- and
- (ii) one —CH═ in one or both pyridine rings in the compound of formula (4) is optionally replaced with —N═.
