Leng, Weinan; Woo, Han Young; Vak, Doojin; Bazan, Guillermo C.; Kelley, Anne Myers published the artcile< Surface-enhanced resonance Raman and hyper-Raman spectroscopy of water-soluble substituted stilbene and distyrylbenzene chromophores>, Formula: C19H34O2, the main research area is SERS hyper Raman substituted stilbene styrylbenzene chromophore.
Surface-enhanced Raman spectra (SERS) are presented for two water-soluble, donor-donor- or donor-acceptor-substituted phenylene vinylene derivatives adsorbed on the surfaces of colloidal silver nanoparticles. The normally water-insoluble, substituted stilbene and distyrylbenzene chromophores have been modified by attaching trimethylammoniumalkyl chains to the amino donor group, creating both aqueous solubility and a net pos. charge that facilitates binding to citrate- or borohydride-reduced silver colloids. A sym. donor-substituted distyrylbenzene exhibits strong electronically pre-resonant SERS spectra that are not highly dependent on excitation wavelength and are qual. similar to the solution-phase resonance Raman (RR) spectra. A donor-acceptor-substituted stilbene exhibits weaker SERS enhancement despite being fully electronically resonant. The spectra vary considerably with excitation wavelength and show new lines not present in the solution-phase spectra, which are attributed to a photoproduct formed on the surface. Two-photon resonant hyper-Raman spectra are also presented for the donor-acceptor stilbene, both with and without surface enhancement.
Journal of Raman Spectroscopy published new progress about Hyper-Raman spectra. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Formula: C19H34O2.
