Fig. 6. Influence of deuteration of pyrrolidine. (a) Structures of deuterated CinNapht 6l and non-deuterated CinNapht 6m. (b) Normalized fluorescence spectra of compounds 6l and 6m in CHCl3 at 25 °C every 30 min over 3 h of irradiation at 470 nm. (c) Absorbance spectra of compounds 6l and 6m in CHCl3 at 25 °C every 30 min over 3 h of irradiation at 470 nm. (d) Table of comparison of photophysical characteristics of CinNaphts 6l and 6m. (e) Comparison of fluorescence intensity decline over time after irradiation at 470 nm.
