The influence of 1,4-butanediamonium-N,N’-dialkyl-N,N,N’,N’-tetramethyl dibromides (CmA, m=7-16 is the number of alkyl carbons) on the egg yolk phosphatidylcholine (EYPC) bilayer thickness and lipid surface area at the bilayer – aqueous phase interface is studied using x-ray diffraction on fluid lamellar CmA+EYPC+HO phases. At the constant CmA:EYPC=0.4 and HO:EYPC=18 molar ratios, the bilayer thickness and the lipid surface area show nonlinear dependencies on the alkyl chain length m with the extremes at m=9.
