Design and compressibility of Langmuir monolayers from organometallic nanocyclic complexes

We propose to control design of organometallic conducting Langmuir monolayer by utilizing geometrodynamic approach. By means of this approach the compressibility of the monolayer, which consists of molecules of thiophene-pyrrole series oligomer with covalently bound hydrophobic alkyl chain, has been analyzed for different subphase with iron salts. It has been discovered that the monolayers are polymerized and turn into monolayers of nanocyclic organometallic coordination compounds at a two-dimensional phase transition of the first order.
