摘要: The spectral and photophysical properties of a new chalcone derivative (2E)-3-[4-(dimethylamino) phenyl]-1-(naphthalen-1-yl) prop-2-en-1-one (DPNP) containing donor-acceptor group has been synthesized characterized on the basis (IR, 1HNMR & 13C NMR) X- ray crystallographic data. effect solvents parameters such as singlet absorption, molar absorptivity, oscillator strength, dipole moment, fluorescence spectra, quantum yield DPNP have investigated comprehensively. Significant red shift was observed in emission spectrum compared to absorption upon increasing solvent polarity, indicating higher moment excited state than ground state. difference between moments (Δμ) were obtained from Lippert-Mataga Reichardts correlations by means solvatochromic method. effects medium acidity electronic spectra studied. interaction with colloidal silver nanoparticles (AgNPs) also studied ethanol ethylene glycol using steady quenching measurements. data reveal that dynamic energy transfer play major role Ag NPs.
