ABSTRACT: Rhodamine 6G-chromone-derived compounds RD1 - RD4 have been synthesized by condensation of rhodamine
6G hydrazide and substituted chromone aldehydes in ethanol using
microwave-assisted reaction. The structures of these synthesized rhodamine 6G
derivatives were confirmed by proton nuclear magnetic resonance (1H-NMR),
carbon nuclear magnetic resonance (13C-NMR), and high-resolution
mass spectra data (HRMS). Colorimetric and photophysical studies show the
synthesized compounds selectively detect copper (II) ion in aqueous
acetonitrile solution.
