We report on the vapor phase adsorption behavior of selected organic molecules onto/into polymer-modified interfaces. We use maleimide−vinyl ether alternating copolymers in conjunction with layer growth chemistry to modify gold-coated substrates with mono- and multilayer polymer structures. The identities of the polymer side groups determine the properties of the polymer interface. We measure the mass uptake of the interface using a quartz crystal microbalance mounted in a chamber where the partial pressure of the organic solvent vapor can be controlled. We interpret the adsorption data in the context of the BET adsorption isotherm. Our results point to the adsorption process depending on both polymer identity and thickness, implying chemical control over the adsorption and desorption kinetics of the process.
