Abstract

[2,2'-Bi-1H-indene]-1,1′-dione-3,3'-dihydroxyl-3,3'-diethyl (1) was found to undergo photochromism in a single crystalline phase from yellow to green. And at the same time a stable organic radical was generated which had been detected by electron spin resonance spectroscopy. The structure of 1 was determined by X-ray cristallographic analysis.
