Langmuir-Blodgett layers of metal complexes of 4,4'-bis-(1-butyl-pentyl)-[2,2']bipyridinyl-6,6'-diamine

The amphiphilic ligand 4,4′-bis-(1-butyl-pentyl)-[2,2′]bipyridinyl-6,6′-diamine (BBPBPDA) was synthesized by the Chichibabin reaction. It formed stable monolayers on the water surface which could be transferred onto solid substrates to construct Langmuir–Blodgett (LB) multilayers. The experimental data obtained by monolayer investigations on the water surface and X-ray investigations on multilayers were compared with the results of molecular modeling. In the presence of transition metal ions, BBPBPDA formed metal complexes with 1:1 stoichiometry. Here, the investigations were focused on complex formation with Cu2+ and the construction of LB multilayers thereof. This was possible by transferring a monolayer of the copper complex formed by an interfacial reaction of the ligand monolayer on an aqueous subphase with dissolved Cu2+ ions to solid substrates as well as by exposing an uncomplexed ligand LB layer to a copper ion containing solution.
