Title:
METHOD FOR THE PREPARATION OF A COATING COMPRISING OLIGOMERIC ALKYNES
Document Type and Number:
WIPO Patent Application WO/2016/174266
Kind Code:
A3
Abstract:
The invention relates to a method for the preparation of a coating comprising at least one coating layer on a substrate, the 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, R' is a tail moiety, (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 to 12, and wherein the head moiety allows for an interaction with the surface of the substrate; b. bringing the monomers into contact with the substrate wherein the interaction of the head moieties of the monomers with the surface of the substrate induces at least a part of the monomers to align in a defined manner thereby forming a film on the surface and bringing the oligoyne moieties of the monomers into close contact with each other; c. inducing a reaction between oligoyne moieties by providing an external stimulus so as to at least partially cross-link the aligned monomers, thereby forming a coating layer on the substrate. The invention further relates to a coating obtainable according to the method of the invention, the use of a coating obtainable according to the method of the invention, a substrate comprising a coating obtainable according to the invention and the use of solid substrate. The invention further relates to a method for the synthesis of the monomers according to the invention.
