Abstract
A new photochromic ZrO2 precursor solution was prepared using zirconium tetra-n-butoxide,
4-(phenylazo)benzoic acid and ethyleneglycol monomethylether. The ZrO2 precursor solution was
irradiated with ultraviolet light (UV) at room temperature. After that, UV-irradiated precursor
solution was irradiated with visible light (Vis) at room temperature. UV-Vis spectra were measured
before irradiation, after UV irradiation and Vis irradiation. Changes of UV-Vis spectra indicated that
the new ZrO2 precursor including 4-(phenylazo)benzoic acid shows photochromism. The
phenomena have synchronized with reversible photoisomerization of 4-(phenylazo)benzoic acid in
the precursor. In addition, the difference of peak position originated from Zr-O CT transition
between before UV irradiation and after UV irradiation increased with increasing the concentration
of 4-(phenylazo)benzoic acid. Furthermore, the optimized structure of the new ZrO2 precursor was
derived by density functional theory (DFT) calculation.
