Oligomers consisting of 10-mesitylanthracene-1,8-diyl units were synthesized by Ni-mediated
coupling of the corresponding dibromide as new oligoarene compounds. The structures
and properties of these oligomers were investigated by NMR and electronic spectroscopy.
Conformational analyses with the aid of DFT calculations revealed that each biaryl
axis adopted a nearly perpendicular conformation, and the trimers and tetramers existed
as a mixture of diastereomeric conformers.
