Two types of half-esters of succinic acid have been prepared. One contains a 1,2-dialkylated glyceryl group, while the other has a normal alkyl group as the hydrophobic group. The mono-molecular films of the half-esters developed at the air-water interface were evaluated by π-A curves. Multilayer Langmuir-Blodgett (L-B) films deposited on the substrate are discussed in terms of pinhole defects. Influences of the surface pressure on accumulation, the number of layers, and the chain length of the lipophilic group are analysed. The L-B film made from the double-chained homologues possessed fewer pinhole defects compared with that composed of the single-chained one.
