Abstract: Abstract The optical properties of 4-methyl-9-(3-oxobutanoyl)-2H,8H-pyrano[2,3-f]chromene-2,8-dione was investigated in solvents of different polarity by employing UV–vis absorption and fluorescence spectroscopy at room temperature (298 K). A bathochromic shift is observed in absorption and fluorescence spectra of… read more here.
