  • Patent number: 10787576
    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.

  • Patent number: 9437753
    Abstract: A device includes a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. The electrical contacts (14) include conductive seeds (16) deposited on the conductive surface (12), an electrically insulating layer (18), which covers discontinuously the conductive seeds (16) in order to form openings leaving access to the conductive seeds (16), and a plating layer (22) recovering the discontinuous insulating layer (18) and deposited on conductive seeds (16) which are accessible through the openings and form points from which the deposit of the plating layer (22) can start. The rest of the conductive surface (12), which doesn't include any electrical contacts (14), is continuously covered by the electrically insulating layer (18).

  • Patent number: 9324505
    Abstract: The invention relates to substituted ullazine and analogs of ullazine as sensitizers for dye-sensitized solar cells (DSSCs) and other photoelectrochemical and/or optoelectronic devices. The sensitizers may comprise donor substituents and/or acceptor substituents, besides an anchoring group suitable for attaching the sensitizer on a semiconductor surface. DSSCs based on this type of sensitizers exhibit high power conversion efficiencies.
