Abstract
A novel 6-butyl-3-[(4-chlorophenyl)diazenyl]-4-hydroxy-2H-pyrano[3,2-c] quinoline-2,5(6H)-dione (dye 2) was
effectively synthesized. The structure of (dye 2) has been set up using its accurate spectral and elemental analysis
statistics. X-ray diffraction (XRD) analysis exhibited that (dye 2) has a polycrystalline nature. Scanning electron
microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were utilized. Optical parameters, as well
as absorption index of (dye 2), were calculated using diffused reflectance wavelength measurements range
200–2300 nm. The bandgap in optics was determined by applying the Kubelka–Munk theory. Two optical band
gap values (2.57 and 2.33 eV) were obtained. The first value (2.57 eV) is responsible for the direct transition
while the other value (2.33 eV) is responsible for the indirect bandgap. AC fields were primarily utilized to
calculate and interpret both AC electrical conductivity, the dielectric constant, and the dielectric loss. Finally
(dye 2) turns out to be efficiently material and may act as a novel solar cell window due to its high bandgap.
