1-19. (canceled)
A conjugated oligomer or polymer comprising at least one unit of Formula (2)
- where n is larger than or equal to 1, A is a spacer that is not N-substituted;
- Ar2 is an opto-electronic functional group selected from a hole injection, a hole transport, an electron injection or an electron blocking group, a backbone group, a photon absorber group, or an emissive group, with the proviso that Ar2 is not oxadiazole or a derivative of oxadiazole or a phosphorescent organometallic complex;
- Ar1 is selected from optionally substituted monocyclic, bicyclic or polycyclic aromatic or heteroaromatic groups.
