Abstract:

Two series of benzoate-ethynylene oligomers bearing cholesteryl- and cholesteryl-6-oxo-hexyl- as mesogen groups were selectively synthesized by a monodirectional interative divergent-convergent approach by the Sonogashira-Heck cross-coupling reaction. These oligomers that are terminated by an acetylene group are of special interest to Dr. Thomas Cooper AFOSR in order to consequently be cross-coupled to platinum complexes to get symmetrical platinumII-2, 4 and 6 benzoate-ethynylene oligomers with potential applications in non linear optics. Their chemical structures were analyzed by 1H, 13C APT, DEPT-135, UV-Vis and fluorescence spectroscopy.
