OG Complex Work Unit Chemistry
wherein:
R1-R32 are each independently selected from:
hydrogen,
deuterium,
halogen,
substituted or unsubstituted alkyl having 1-20 carbon atoms,
substituted or unsubstituted cycloalkyl having 3-20 carbon atoms,
substituted or unsubstituted alkoxy having 1-20 carbon atoms,
substituted or unsubstituted aryl having 6-30 carbon atoms, substituted or unsubstituted heteroaryl having 3-30 carbon atoms, and
cyano;
Ar1 and Ar2 are independently selected from an aromatic group having 6-14 carbon atoms and an heteroaromatic group having 3-12 carbon atoms, respectively;
heteroatom in the heteroaromatic group is selected from one or more of O, S and N; and
the substitution is chosen from the group consisting of substitution by deuterium, halogen and C1-8 alkyl.
