Fig. 3.11 Photographs of a (rac)-1G and c (S)-1G crystals and the corresponding crystals of
b (rac)-1G and d (S)-1G obtained after heated at 65 °C for 1 h under vacuum. These photographs
were taken under UV irradiation at 367 nm at room temperature under air
Fig. 3.12 1 H-NMR spectra of a (rac)-1G obtained before and after heating at 65 °C for 1 h and
b (S)-1G obtained before and after heating at 65 °C for 1 h dissolved in CDCl3
Fig. 3.13 Emission spectra of a a (rac)-1G before (black line) and after heating at 65 °C for 1 h
(light green line) and b (S)-1G before (black line) and after heating at 65 °C for 1 h (green line).
Excitation wavelength is 365 nm
