Complexation of Ferrous and Cupric Ions by Phenanthroline and Terpyridine Langmuir Films.

Date Published:



The complexation of FeII and CuII 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 CuII had a pronounced effect on the isotherm consisting of phenanthroline moieties forming a square-planar 1:2 (CuII/phenanthroline) complex. However, FeII affected the isotherm made of 1:1 phenanthroline/terpyridine amphiphiles as a result of forming a pentacoordinate complex. [on SciFinder(R)]
