“…As a part of a systematic study on the complexation properties of Langmuir monolayers we report the results obtained using as amphiphilic molecule a double-chain dithiocarbamate. Dithiocarbamates are chelating reagents which coordinate the metal ion through sulfur atoms of two different molecules [4], recent studies have also shown that nickel(II) and copper(II) complexes of these compounds are powerful ozone deactivators [3]. We studied the characterization of dioctadecyldithiocarbamate monolayers and the complexation of a bivalent metal ion, nickel (II), present in the aqueous subphase measuring surface pressure and surface potential-area isotherms.…”

“…The study of the interactions of these supramolecular structures with metal ions is particularly important to develop new materials in the field of chemical sensors by means of the Langmuir-Blodgett technique. In fact, the investigation of the interfacial eomplexation process eventually leads to the realization of fiber optic sensors for the (*) Paper presented at the I International Conference on Scaling Concepts and Complex Fluids, Copanello, Italy, July 4-8, 1994. detection of transition metals in polluted waters or toxic gases [2,3].

(ricevuto il 28 Ottobre 1994)Summary. --Oriented systems such as monolayers and Langmuir-Blodgett multilayers constitute supramolecular structures appropriate for ion detection. In fact, they are sensitive to small quantities of ions since they have specifically oriented ligand head groups that can easily combine with the ions to be detected in solution. We investigated monolayers of dioctadecyldithiocarbamate (DODTC) specifically synthesized and we studied the interactions of the monolayers with transition metal ions such as Ni 2+ dissolved in the subphase. The spreading isotherms, the surface potential-area isotherms and the spectroscopic measurements (UV-Vis absorption and ESCA spectroscopy) show that the metal ions can combine with the DODTC monolayers. The present findings show that it is possible to employ these systems to build chemical sensors for transition metal ions. PACS 68.10 -Fluid surfaces and fluid-fluid interfaces.
