Dynamics of the Spiropyran-Merocyanine Conversion in Solution

The photoinduced processes leading to the isomerization and complexation which preceed spontaneous aggregation are investigated for 1-(β-methacryloxyethyl)-3,3-dimethyl-6'-nitrospiro(indoline-2,2'-benzopyran) (SP) by picosecond and nanosecond transient absorption spectroscopy in toluene and acetonitrile.By monitoring the light (wavelength and intensity) and concentration dependences of the species produced upon photoexcitation of the ring-closed from (SP-A) a mechanism was developed which accounts for the formation of colored species in the picosecond to microsecond time domain.In toluene and methylcyclohexane colored species are formed by two routes: isomerization of a species X, in which the spiro C-O bond is broken (but the nonpolar geometry of the parent is retained) to a ring opened form B and secondly by a bimolecular reaction of the ??* triplet of SP-A with a ground-state molecule to form a complex AB.In acetonitrile radiationless deactivation of X is favored and only one colored form AB is produced.
