1. An organometallic compound, having a structural formula as shown in Formula I:

OG Complex Work Unit Chemistry
wherein:
one in A1 to A4 is a C—C bond connected with a ring E, one is a C-M bond connected with metal M, one is CR4, and another is CR0 or N;
one in A5 to A8 is CR3, and the other three are independently represented as CR0 or N;
M is a metal with the atomic weight greater than 40;
R0 to R4 are independently selected from hydrogen, deuterium, halogen, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, a substituted or unsubstituted C1 to C10 heteroalkyl group, a substituted or unsubstituted C6 to C30 aralkyl group, a substituted or unsubstituted C1 to C10 alkoxy group, a substituted or unsubstituted C6 to C30 aryloxy group, an amino group, a substituted or unsubstituted C1 to C10 silyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C1 to C8 heteroaryl group, a cyano group, a isocyano group, or a phosphino group, wherein the substitution refers to substitution by deuterium, F, Cl, Br, a C1 to C4 alkyl group, a C1 to C4 alkoxy group, a C3 to C6 cycloalkyl group, an amino group substituted by a C1 to C4 alkyl group, a cyano group, a isocyano group or a phosphino group;
at least one of R3 and R4 is not hydrogen;
Z is independently selected from O, S, Se, C(R)2, Si(R)2, NR, BR or POR, wherein R is independently selected from a substituted or unsubstituted C1 to C10 alkyl group or a substituted or unsubstituted C1 to C10 alkoxy group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C6 to C 30 aryl group, a substituted or unsubstituted C1 to C18 heteroaryl group; and
X-Y is a monoanionic bidentate ligand, wherein the sum of a and b equals to a valence state of the metal M.
