An efficient synthetic route to construct particular papilionaceous molecules containing oligobenzofurans is described. The key steps involved composing the backbone of the molecules by the Sonogashira cross-coupling reaction, followed by closing the benzofuran ring under alkaline conditions, and further aromatic cyclization of a multi-benzofuranyl precursor using ferric chloride as the oxidative reagent. Basic optical studies (UV-Vis, fluorescence, and fluorescence quantum yield) have been carried out on the synthesized molecules.
