Abstract:
Absorption and emission spectra of the merocyanine (MC) form of 6- nitrobenzospiropyran (SP), as well as the kinetics of the thermal decay of MC to SP, were measured in solvent mixtures of ethanol-hexane, ethanol-toluene and acetonitrile-toluene. For all these mixtures, the Stokes shift of MC shows the same linear dependence with the solvent parameter E(T)(30). The thermal decay kinetics is monoexponential in acetonitrile-toluene mixtures and biexponential in those containing ethanol. The activation parameters of the rate constants display very different behaviours with E(T)(30): whereas ΔG≠ is linear in this parameter, E(a) shows abrupt variations with this polarity parameter. This is compensated by changes in ΔS≠, resulting in a linear correlation between E(a) and ΔS≠.
