The results have indicated that the introduction of electron-donating methoxy or electron-withdrawing cyano-group at the 7-position of 3-phenylcoumarins caused a bathochromic shift for both absorption and fluorescence spectra. The phenyl group at the 4-position derivative has a hypsochromic shift for both absorption and fluorescence spectra.
