Abstract
Polymeric amphiphiles (I n ) containing poly(methacrylic acid) (PMAA) segments having different chain lengths (n=35, 63, and 177) and two long alkyl chains whose ends are modified with disulfide groups are newly prepared. It is shown that these polymers successfully form spontaneously-adsorbed monolayers on gold substrates from aqueous solutions with different pHs and that the adsorption processes as well as the film thicknesses and lateral molecular orientation of the resulting monolayers are governed by the conformational size and/or the chain length of the PMAA segment during the adsorption
