Thiophene- and bithiophene-based π-conjugated Schiff base oligomers containing binaphthalene moieties in the backbone. Properties and computational simulations

Schiff base oligomers based on a binaphthalene core were synthesized from [1,1′-binaphthalene]-4,4′-diamine with thiophene-2,5-dicarbaldehyde and [2,2′-bithiophene]-5,5′-dicarbaldehyde by a high-temperature polycondensation method.
