1. A photoactive compound having the formula:

OG Complex Work Unit Chemistry
wherein X is N or C-R, wherein M is a metal atom with a stable +2 oxidation state, wherein each R is independently H, F, Cl, Br, I, CF3, CN, a substituted silyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted 5-membered ring, a substituted or unsubstituted 5-membered heterocyclic ring, a substituted or unsubstituted 6-membered ring, a substituted or unsubstituted 6-membered heterocyclic ring, or a substituted or unsubstituted fused ring, wherein at least one R comprises

OG Complex Work Unit Chemistry
wherein Y1 and Y2 are independently selected from CH, NH, alkyl substituted N, alkyl substituted Si, O, S, Se, or Te, wherein each R1 is independently H, F, Cl, Br, I, CH3, CF3, C(CH3)3, CH(CH3)2, OCH3, Si(CH3)3, or R1 and R1 together form a 5-membered substituted or unsubstituted ring, or a 6-membered substituted or unsubstituted ring, and wherein each A ring independently comprises a 5-membered ring, a 6-membered ring, or a fused ring group including non-aromatic, aromatic, or heteroaromatic ring moieties.
