Abstract
Abstract Process for producing a film having at least one monomolecular layer of non-amphiphilic molecules. This process comprises the following stages: (a) combining non-amphiphilic molecules A, such as pyridine, with amphiphilic molecules B, such as a zinc porphyrin, in order to form a complex of molecules A and B; (b) forming on the surface of the liquid a monomolecular layer of the thus obtained complex, and (c) transferring the thus formed monomolecular layer to a rigid support. Molecules A and B can form between them a charge transfer complex, e.g. TCNQ-alkyl pyridinium which makes it possible to obtain laminated structures of organic conductors.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A process for producing a thin film having at least one monomolecular layer of nonamphiphilic molecules A, which comprises the steps of: (a) combining said non-amphiphilic molecules A with amphiphilic molecules B thereby forming a complex of molecules A and B, said amphiphilic molecule B being depositable on a support in the form of the monomolecular layer by the Langmuir-Blodgett method; (b) forming on the surface of the liquid employed in the Langmuir-Blodgett technique a monomolecular layer of the thus obtained complex; and (c) transferring the thus formed monomolecular layer to a rigid support.
Claim 2
Dependent Claim
94 words
A process for producing a thin film having at least one monomolecular layer of nonamphiphilic molecules A, which comprises the steps of: (a) combining said non-amphiphilic molecules A with amphiphilic molecules B thereby forming a complex of molecules A and B, said amphiphilic molecule B being depositable on a support in the form of the monomolecular layer by the Langmuir-Blodgett method; (b) forming on the surface of the liquid employed in the Langmuir-Blodgett technique a monomolecular layer of the thus obtained complex; and (c) transferring the thus formed monomolecular layer to a rigid support.
Claim 3
Dependent Claim
33 words
