To understand how substituent variations influence the fluorescence properties of pyrene-chromone Schiff base derivatives.
Synthesis of three novel pyrene-chromone Schiff base derivatives via condensation.
Characterization using FT-IR, 1H-NMR, and mass spectrometry.
Photophysical behavior analyzed through UV-Vis and fluorescence spectroscopy.
Concentration-dependent absorption studies assessed using Beer–Lambert law.
Intense absorption observed in the 430–440 nm range with emission between 540–565 nm.
Large Stokes shifts of 107–125 nm noted in fluorescence readings.
Substituent effects altered optical band gaps and fluorescence intensities, with nitro-substituted derivatives showing reduced band gap and quenching.
Beer–Lambert behavior confirmed absence of aggregation in samples.
