10-phenanthroline-based (A–D–A–D–A) and oligothiophene-based (A–D–D–D–(D)–A) heterocyclic aromatic fluorescencecompoundshaving N-containing imidazole and pyridine tails with effective π-conjugated systems, prepared by the combination of carbon–carbon (C–C) bond and carbon–nitrogen (C–N) bond cross-coupling reactions, is described. They have molecular lengths of more than 2.30 nm in the cases of 4, 6, 9, and
