Abstract
A photochromic organic compound A is a compound that undergoes a major reversible color change on irradiation at an appropriate wavelength (λa) to form a more highly colored species B, which undergoes the reverse reaction either thermally or photochemically on irradiation at a second wavelength (λb):
