Fig. 5.18 UV/vis absorption (black solid line), excitation (green dotted line, λ em = 419 nm), and
emission spectra (green solid line, λ ex = 240 nm) of 3 in CH 2 Cl 2 (c = 1.79 × 10 −6 M) at room
temperature
Fig. 5.19 Photographs of a a crystal of 3G/MeOH upon heating to 30 °C for 10 min and b an orangeemitting crystal showing the recovery of the green emission upon exposure to high concentrations
of MeOH vapor. Photographs and emission spectra were taken under UV light (365 nm). c Emission
spectra of 3G/MeOH (green line), 3O heat (red line), 3O scsc (orange line), and 3G re /MeOH (black
