W. published the artcile< Photodimerization processes in self-assembled chiral oligo(p-phenylenevinylene) bolaamphiphiles>, Formula: C19H34O2, the main research area is photodimerization self assembled chiral oligo phenylenevinylene bolaamphiphile; monolayer surfactant stereoselective photochem cycloaddition.
An oligo(p-phenylene vinylene) (OPV) amphiphile has been synthesized with a pos. charged head group on one end and a hydrophilic ethyleneglycol wedge on the other. In water, this bolaamphiphile forms vesicles consisting of a monolayer in which the OPV surfactants are organized in a helical head-to-tail fashion. Mass spectrometry anal. and reversed-phase high performance liquid chromatog. (RP-HPLC) reveals that because of the presence of two double bonds in the OPV units, photo-induced [2+2] cycloaddition takes place resulting in polymerization of the surfactants. Performing RP-HPLC allowed the OPV dimer to be isolated in a sufficient amount to perform a variety of one- and two-dimensional NMR experiments These experiments show a highly stereoselective photochem. cycloaddition process resulting in a regioselective head-to-tail dimerization with a stereoselective syn arrangement.
