Abstract

Starting from bromo-substituted 2, 2′-bipyrimidine or 1, 10-phenanthroline building blocks, the preparation in a first step of ethynyl grafted molecules allows the production in a second step of multitopic ligands by cross-coupling with difunctionalised chelating molecules. Various combinations allow the interconnection of bipyrimidine to terpyridine, pyrene, or phenanthroline fragments. When two alkyne functions are present, a simple protocol gives ...
