fluorescence quenching and fluorescent color changes were obviously observed with increasing water content. The experimental results revealed that the hydroxyl groups substituted at the 8-position of HQCT and HQPH played a key role in the fluorescence emission processes. Dynamic light scattering (DLS) and 1H NMR titration indicated that the sensing mechanism for the detection of water was based on inhibition
Two mononuclear PdII complexes and a heterodinuclear PdII/RuII complex bearing the hydrazone-derived ligand were prepared and their structures and properties were characterized.
