Abstract

The complexation of Fe^II and Cu^II ions by phenanthroline and terpyridine-based Langmuir films was studied by the effect the added ions in the subphase on the isotherms. We found that Cu^II had a pronounced effect on the isotherm consisting of phenanthroline moieties forming a square-planar 1:2 (Cu^II/phenanthroline) complex. However, Fe^II affected the isotherm made of 1:1 phenanthroline/terpyridine amphiphiles as a result of forming a pentacoordinate complex.
