A simple synthetic route for the efficient preparation and purification of two regioisomers of a pyrene derivative containing two ethynyl groups―1,6‐ and 1,8‐bis(ethynyl)pyrene―is described. The former compound was used as a building block for the stepwise synthesis of a highly conjugated, ditopic bis(2,2'‐bipyridine) ligand ( 2 ) containing the pyrene nucleus at the central core. The fluorescence properties of ligand 2 are reported. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
