Pyridine-2,6-dicarboxamide-based scaffolds have been extensively used for coordinating assorted metal ions. It's believed that the presence of a chelating cavity endows such scaffolds towards metal binding. However, if the chelating cavity could also incorporate with a suitable fluorophore; then scaffolds may offer significant sensing possibilities. In this work, we present pyridine-2,6-dicarboxamide-based fluorescent probe, offering a chelating cavity that is incorporated with fluorenyl moieties as fluorophores. The synthesis of desired fluorescent chemosensor will be reported in details and their structures will be characterized by melting point, 1H NMR, and 13C NMR spectroscopy.
