Abstract
Abstract 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 ...
