摘要

Organic compounds (I), are new, where: (I) are introduced as ink molecules on the substrate surface by stamp-like printing; (I) bind on the surface with its main end of the molecule; (I) have a surface structure with the intended functional characteristics on the surface under self-organization; and the ink molecules contain two independent main groups for binding on different materials of substrate surfaces and are functionalized after its binding on the substrate surface by sequential chemical process. Organic compounds of formula (Y1-(Z) n-X-(Z) m-Y2) (I), are new, where: (I) are introduced as ink molecules on the substrate surface by stamp-like printing; (I) bind on the surface with its main end of the molecule; (I) have a surface structure with the intended functional characteristics on the surface under self-organization; and the ink molecules contain two independent main groups for binding on different materials of substrate surfaces and are functionalized after its binding on the substrate surface by sequential chemical process. Y1, Y2 : different functional main groups of the molecule for binding on a specific substrate surface, e.g. thiol, phosphonate or phosphonic acid; X : cleavable groups for the separation of the molecule, containing a carboxylic acid derivative, such as ester, anhydride, imide or urethane, except amides; (Z) n, (Z) mbinding chain between the respective main groups and the cleavable groups; and n, m : 1-18. Independent claims are included for: (1) process for use of the organic molecules for the functionalization of a substrate surface, comprising applying the organic molecules (ink-molecules) on a substrate surface to be functionalized and forming a bond with the substrate surface over one of the both main groups of the ink molecules, where after the binding of the ink molecules on the substrate surface, the cleavable group of the ink molecules is cleaved on the substrate surface and the separated part of the ink molecules, which are unbound on the substrate surface over its main group, are removed; and (2) bonding the surfaces of various materials, comprising binding the organic compounds (ink molecules) with their main groups on surfaces of various materials e.g. gold, in which one main group of each ink molecule binds on a first surface and the other main group binds on a second surface.
