Pyrene and its derivatives exhibit thermal stability, high extinction coefficients, excimer formation, high photoluminescence, long fluorescence lifetime, fluorophoric properties and enhanced charge carrier mobility which make them find applications in optoelectronic area and are useful as large planar synthetic building blocks in supramolecular chemistry. One of the approaches to overcome this downside is the introduction of bulky aryl/alkyl substituents or incorporation heteroatoms into the π-extended conjugated system of pyrene. In this work, Some new derivatives of 4-Aryl-2, 6-di(pyren-1-yl)pyridines have been synthesized through one-pot reaction and were formed with cyclization of Arylaldehydes, 1-acetylpyrene and ammonium acetate in acetic acid. The products were confirmed by FT-IR, Mass, 1H-NMR, 13C-NMR and elemental analysis. These new compounds were subsequently studied for their fluorescence properties.
