Patent ID: 8053575

Claim:
A nitrogen-containing heteroaromatic ligand-transition metal complex, represented by the following Formula (1): [R 1 —X—R 2 ].[M(Y) m ] − Formula (1) wherein, X is represented by the following Formula (2): each of R 1 and R 2 is independently selected from the group consisting of a substituted or unsubstituted alkyl group of about 1 to about 30 carbon atoms; a substituted or unsubstituted hetero alkyl group of about 1 to about 30 carbon atoms; a substituted or unsubstituted alkoxy group of about 1 to about 30 carbon atoms; a substituted or unsubstituted hetero alkoxy group of about 1 to about 30 carbon atoms; a substituted or unsubstituted aryl group of about 6 to about 30 carbon atoms; a substituted or unsubstituted arylalkyl group of about 6 to about 30 carbon atoms; a substituted or unsubstituted aryloxy group of about 6 to about 30 carbon atoms; a substituted or unsubstituted hetero aryl group of about 2 to about 30 carbon atoms; a substituted or unsubstituted hetero arylalkyl group of about 2 to about 30 carbon atoms; a substituted or unsubstituted hetero aryloxy group of about 2 to about 30 carbon atoms; a substituted or unsubstituted cycloalkyl group of about 5 to about 20 carbon atoms; a hetero substituted or unsubstituted cycloalkyl group of about 2 to about 30 carbon atoms; a substituted or unsubstituted alkylester group of about 1 to about 30 carbon atoms; a substituted or unsubstituted hetero alkylester group of about 1 to about 30 carbon atoms; a substituted or unsubstituted aryl ester group of about 6 to about 30 carbon atoms; and a substituted or unsubstituted hetero aryl ester group of about 2 to about 30 carbon atoms, M is a transition metal atom selected from the group consisting of gold (Au), copper (Cu), palladium (Pd) and platinum (Pt), and the transition metal atom forms a complex with a nitrogen atom of the substituted or unsubstituted nitrogen-containing heteroaromatic organic group, Y is selected from the group consisting of a halide, a hydroxyl group, and an acetate functional group (OAc), and m is an integer of about 3 to about 4.
