Abstract

The extraordinary stability of the photoinduced red form of a cationic spiropyran is used for obtaining in situ X-ray diffraction evidence of its molecular structure. The density functional theory calculations have shown that the stabilization of the red form of the cationic relative to the neutral spiropyran is thermodynamically controlled, through compensation of the charge within the zwitterion by the methylpyridinium group.
