"Encapsulation of Diphenylmethyl Phosphonium Salts in Reverse Micelles: Enhanced Bimolecular Reaction of the Photofragments"
Christian F. Sailer, Rupashree Balia Singh, Johannes Ammer, Eberhard Riedle, and Igor Pugliesi
Chem. Phys. Lett. 512, 60-65 (2011)


Abstract:
We investigate the effects of encapsulation on the dynamics after photoinduced bond cleavage of a diphenylmethyl phosphonium salt in acetonitrile reverse micellar nanopools by femto-second UV/Vis transient absorption. The small volume of the nanopool is just large enough to accommodate one precursor molecule and therefore eliminates the effects of diffusion present in bulk solution. The tight environment keeps the fragments together and prolongs the time for geminate recombination to occur. We therefore observe an enhanced yield of this bimol-ecular reaction of the ground state photofragments.
