Oligomeric and polymeric OLED materials produced via arylation of quinones

An oligomeric para-phenylene compound having the formula:

• R1—(Ari)n—R2
• wherein
• the subscript n is 5;
• each Ari group is a substituted or unsubstituted aryl group, with at least one Ari group being selected from phenylene having from 1 to 4 halogen substituents;
• R1 and R2 are each substituents that increase the solubility of the para-phenylene compound in nonpolar organic solvents relative to the solubility of the corresponding compound and wherein R1 and R2 are each independently substituents having the formula:
• R3—(Arj)m—
• wherein
• the subscript m is 1;
• each Arj is substituted or unsubstituted phenylene and
• R3 is selected from the group consisting of H, substituted or unsubstituted (C1-C12) alkyl, substituted or unsubstituted (C1-C12) alkylamino, substituted or unsubstituted (C1-C12) alkylthio, substituted or unsubstituted di(C1-C12) alkylamino, substituted or unsubstituted arylamino and substituted or unsubstituted diarylamino;
• and
• with the proviso that the Ari groups are linked together in a 1,4 -paraphenylene manner.
