Patent ID: 8431246

Claim:
An organic metal complex derivative represented by the following Formula 1 or 2: wherein Y is a ligand containing n is 1 or 2, M is aluminum, L is wherein X is Deutrium or Fluorine, m is 1 to 5, O is oxygen, A is formed in that it is substituted with oxygen and a benzene group which is substituted with the X, wherein the A may be selected from the group consisting of a C 2 ˜C 40 alkenylene group unsubstituted or substituted with one or more groups selected from the group consisting of halogen, deuterium, an amino group, a nitrile group, a nitro group, a C 1 ˜C 40 alkyl group, a C 2 ˜C 40 alkenyl group, a C 1 ˜C 40 alkoxy group, a C 3 ˜C 40 cycloalkyl group, a C 2 ˜C 40 heterocycloalkyl group, a C 6 ˜C 40 aryl group and a C 5 ˜C 40 heteroaryl group; an amino group unsubstituted or substituted with one or more groups selected from the group consisting of halogen, deuterium, an amino group, a nitrile group, a nitro group, a C 1 ˜C 40 alkyl group, a C 2 ˜C 40 alkenyl group, a C 1 ˜C 40 alkoxy group, a C 3 ˜C 40 cycloalkyl group, a C 2 ˜C 40 heterocycloalkyl group, a C 6 ˜C 40 aryl group and a C 5 ˜C 40 heteroaryl group; a C 6 ˜C 40 arylene group unsubstituted or substituted with one or more groups selected from the group consisting of halogen, deuterium, an amino group, a nitrile group, a nitro group, a C 1 ˜C 40 alkyl group, a C 2 ˜C 40 alkenyl group, a C 1 ˜C 40 alkoxy group, a C 3 ˜C 40 cycloalkyl group, a C 2 ˜C 40 heterocycloalkyl group, a C 6 ˜C 40 aryl group and a C 5 ˜C 40 heteroaryl group; and a C 5 ˜C 40 heteroarylene group unsubstituted or substituted with one or more groups selected from the group consisting of halogen, deuterium, an amino group, a nitrile group, a nitro group, a C 1 ˜C 40 alkyl group, a C 2 ˜C 40 alkenyl group, a C 1 ˜C 40 alkoxy group, a C 3 ˜C 40 cycloalkyl group, a C 2 ˜C 40 heterocycloalkyl group, a C 6 ˜C 40 aryl group and a C 5 ˜C 40 heteroaryl group, or may form an aliphatic, aromatic, heteroaliphatic, or heteroaromatic condensed ring or a spiro bond, together with the adjacent group, wherein Y, n and M are the same as defined in Formula 1, 1 is 2, L 1 is wherein X is Deutrium or Fluorine, m is 4 O is oxygen, A and A′ are each independently the same as or different from each other, and the same as defined in the A in the Formula 1.
