Abstract The amphiphilic ligand 4,4&#x2032;-bis-(1-butyl-pentyl)-[2,2&#x2032;]bipyridinyl-6,6&#x2032;-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&#x2013;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 Cu<sup>2+</sup> 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 Cu<sup>2+</sup> ions to solid substrates as well as by exposing an uncomplexed ligand LB layer to a copper ion containing solution.
