6 Thermo-Responsive Phosphorescence Control Mediated …
Fig. 6.19 DSC profiles of
a the crystal 1 and b 2.
Heating and cooling rates
were 5 °C/min, respectively.
There were no exo- or
endothermic peaks in the
both crystalline samples
6.9.9 Photophysical Properties
Emission spectra and decay traces were obtained using an FLS 920 spectrometer from
Edinburgh Instruments equipped with a micro halogen lamp (μF). For phosphorescence emission spectra, we used 370 nm as the excitation wavelength and detected
emission from 400 to 700 nm. For phosphorescence decay trace, we used 370 nm
as the excitation wavelength and detected kinetic traces at 498 and 543 nm. For low
temperature measurements, we used a custom-made NMR tube Dewar to vary the
temperature using different cooling baths. Approximately 8 mg of the solid sample,
which was grinded to a find powder, was placed inside an NMR tube and the NMR
tube was placed inside the Dewar for low temperature measurements (Figs. 6.26,
6.27 and 6.28).
