Disclosed are iridium-based luminescent compounds having phenylpyridine moieties with an organosilicon group, and organic electroluminescence devices using the compounds as color-producing materials. The luminescent compounds have the structure of Formula 1 below:
wherein L 1 , L 2 , L 3 , R 1 , R 2 and R 3 , which may be identical to or different from each other, are each independently selected from the group consisting of aryl, alkoxy, alkyl, and groups of Formulae 2 and 3 below:
wherein D 1 , D 2 and D 3 are each independently selected from the group consisting of C 1~18 alkyl, C 1~18 alkoxy, substituted or unsubstituted C 1~18 alkyl and allyl, and substituted or unsubstituted C 6~18 fluorinated alkyl and allyl groups;
wherein D 4 , D 5 and D 6 are each independently selected from the group consisting of C 1~18 alkyl, C 1~18 alkoxy, substituted or unsubstituted C 1~18 alkyl and allyl, and substituted or unsubstituted C 6~18 fluorinated alkyl and allyl groups.
