Effects of Cu(II) on the Formation and Orientation of an Arachidic Acid Langmuir-Blodgett Film.

The influence of the copper (II) ion on the formation, morphology, and organization of an arachidic acid monolayer was investigated using Langmuir-Blodgett (LB) monolayers, -A isotherms and Brewster angle microscopy (BAM). Our findings indicate that a Cu2+-complexed LB film exhibits order that depends on the subphase pH, analogous to other metal ions.1-2 The metal ion facilitates formation of solid-phase films at surface pressures as low at 5 mN/m. The films exhibit a rigid, ordered phase, evidenced by the absence of a collapse point and an increase in surface pressure rather than the typical sharp decrease in surface pressure indicative of film failure. The role of amphiphile ionic charge vs. pH (i.e., the extent of arachidic acid protonation) plays a role in the observed absence of collapse and the ability of the films to maintain order and cohesion at high surface pressures (ca. 65 mN/m). Additionally, film thickness data suggest that the incorporation of Cu2+ ions induces a change in orientation of the aliphatic chains of the amphiphiles, and that amphiphile solubility in the subphase may play a role in the observed film behavior at low surface areas and high pH.
