Ramazan Kocak Arif Dastan Department of Chemistry, Faculty of Sciences, Atatürk University, Erzurum, 25240, Turkey 10.3762/bjoc.17.61 Abstract The synthesis of novel polycyclicπ-conjugateddihydropyridazines, pyridazines, and pyrroles was studied. Dihydropyridazine dyes were synthesized by
obtained gave absorbance and emission at long wavelengths.
