ResumoLangmuir-Blodgett (LB) multilayers were prepared from disc-shaped multiyne mesogens based on amphiphilic alkyl pentakis (aryl-ethynyl) benzene ethers. 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 analyzed 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.
