Numerous works have been devoted to the design of new fluorescent sensors for various applications such as clinical toxicology, environmental bioorganic chemistry and waste management. To develop optical molecular probes or sensors for toxic metals, ruthenium complexes with ditopic 1,10-phenanthrolines seem to be an appropriate solution. Moreover, aminoquinolines possess good fluorescent properties but have not yet been investigated as a signaling subunit in chemosensors. In this work, Pd-catalyzed amination of 3-bromo-1,10-phenanthroline (1) and 6-bromoquinoline (2) with linear polyamines was investigated to prepare fluorescent receptors.
