The thermally stable photochemically fatigue resistant title compound and its coloured form provide a photochromic system well suited for chemical actinometry in the near-u.v. and visible spectral regions.A solution of the photochromic compound in many common organic solvents can be used repeatedly and, provided the stirred solution absorbs all the incident radiation, the radiant flux can be determined simply by measuring an absorbance change.
