Abstract
A series of new heterocyclic chromophores 3–6 were synthesized in moderate to excellent yields by condensation of 5,6-phenantroline-dione with formyl-thiophene derivatives 1–2 in the presence of ammonium acetate in glacial acetic acid. These chromophores possess an (oligo)thienyl π-conjugated system attached to an imidazo-phenanthroline moiety. These derivatives were evaluated concerning their solvatochromic properties, thermal stabilities, and molecular optical nonlinearities.
