Effect on solvent polarity and concentration on the photo transformation of 6-nitro BIPS
Polar and non-polar solvents; ethanol and toluene respectively were used to dissolve and investigate the photochromism behavior of 6-nitro BIPS at different solvent concentration. Absorption spectra of 6-nitro BIPS in low concentration solvent were arising to absorption peak of 530nm and 600nm...

| Summary: | Polar and non-polar solvents; ethanol and toluene
respectively were used to dissolve and investigate the
photochromism behavior of 6-nitro BIPS at different solvent
concentration. Absorption spectra of 6-nitro BIPS in low
concentration solvent were arising to absorption peak of 530nm
and 600nm after UV irradiation for ethanol and toluene
respectively. At high concentration solvent of 6-nitro BIPS, the
absorption spectra did not present any changes on absorption
peak after UV irradiation whereas the absorption peak was
remains at 530nm for ethanol and no absorption peak appeared
for toluene. Shifting of 6-nitro BIPS wavelength spectrum from
530nm for dilution in ethanol to 600nm for dilution in toluene in
low concentration solvent was observed and investigated. |
