A novel biindenylidenedione compound, [2,2′‐bi‐1 H ‐indene]‐3,3′‐bis [(4‐oxo‐4‐ferrocenylbutanoyloxy)propyl]‐3,3′‐ dihydroxy‐1,1′‐dione was synthesized and characterized fully by 1 H NMR, IR, MS and elemental analysis. The photochromic and photo‐induced radical properties were investigated by means of UV–vis and electron spin resonance spectroscopy, respectively. The results show that the title compound simultaneously exhibits photochromism in the solid state as well as generating stable free radicals under irradiation with 330 nm light. This fact provides evidence for the photochromic mechanism of this kind of compounds. Copyright © 2008 John Wiley & Sons, Ltd.
