The two compounds used are characterized by five hydrophobic flexible chains and one hydrophilic substituent at the terminal position of the alkoxy chain. The LB films were analysed by X-ray scattering and spectroscopic measurements. An edge-on arrangement of the two discotic pentaalkynes within Y-type bilayers with a different packing density proved to be possible for the LB films of both compounds.}, language = {en} } @article{SchneiderKoehler1992, author = {Schneider, Ingo and K{\"o}hler, Brigitte}, title = {Amitrole tolerance in cell and tissue cultures and regenerated plants from Nicotiana plumbaginifolia : II.
