Method for the preparation of a coating comprising oligomeric alkynes

A method for the manufacture of a coating comprising at least one coating layer on a target substrate, said method comprising the steps of

• a. providing monomers of the type R—(N)x-(L)m-(C≡C)n-(L′)o-(N′)y-R′, wherein
• R is a head moiety wherein R is selected from the group consisting of phosphoric acid and its derivatives, phosphate and its derivatives, carboxy, ester, hydroxyl, mercapto, oligoethylenoxy, oxiranyl, trihalosilyl, and trialkoxysilyl,
• R′ is a tail moiety wherein R′ are selected from the group consisting of unbranched alkyl, unbranched perfluoroalkyl, phosphonic acid and its derivatives, phosphate and its derivatives, mercapto, oligoethylenoxy, oxiranyl, trihalosilyl, and trialkoxysilyl,
• (C≡C)n is an oligoyne moiety,
• L and L′ are linker moieties,
• N and N′ independently are branched or unbranched optionally substituted C1-C25 alkyl moieties optionally containing 1 to 5 heteroatoms,
• x, m, o, and y are independently 0 or 1,
• n is 4, 5, 6, 7, or 8, and
• wherein said head moiety allows for an interaction with the surface of an auxiliary substrate and/or with the surface of said target substrate;
• b. bringing said monomers into contact with said auxiliary substrate wherein said interaction of said head moieties of said monomers with the surface of said auxiliary substrate induces at least a part of said monomers to align in a defined manner thereby forming a film on said surface of said auxiliary substrate and bringing said oligoyne moieties of said monomers into close contact with each other;
• c. optionally, reducing the surface area of said surface of said auxiliary substrate;
• d. depositing a layer of the target substrate on said film;
• and
• e. inducing a reaction between oligoyne moieties by providing an external stimulus so as to at least partially cross-link said aligned monomers, thereby forming a coating layer on said target substrate,
• wherein said auxiliary substrate is a liquid substrate.
