Patent number: 8765882Abstract: New monomers, polymers, and blends of polymers with an electron acceptor are provided, e.g., for use in a photovoltaic device. The electron acceptor can be a fullerene derivative and the polymer can comprise monomer units according to the formula: wherein L? is L-C(O)O-J, L-C(O)NR?-J, L-OCO-J?, L-NR?CO-J?, L-SCO-J?, L-O-J, L-S-J, L-Se-J, L-NR?-J or L-CN; L is a linear or branched alkylene group having from 1 to 10 carbon atoms; J is a hydrogen atom or a linear or branched alkyl group having from 1 to 4 carbon atoms; J? is a group having from 1 to 10 carbon atoms, being saturated or unsaturated, linear or branched, optionally comprising a phenyl unit; and R? is a hydrogen atom or a linear or branched alkyl group having from 1 to 4 carbon atoms.Type: GrantFiled: June 8, 2012Date of Patent: July 1, 2014Assignees: IMEC, Universiteit HasseltInventors: Laurence Lutsen, Dirk Vanderzande, Bert Campo

Patent number: 8759444Abstract: Disclosed are multichromophores, and methods, articles and compositions employing them. Disclosed are methods, articles and compositions for the detection and analysis of biomolecules in a sample. Provided assays include those determining the presence of a target biomolecule in a sample or its relative amount, or the assays may be quantitative or semi-quantitative. The methods can be performed on a substrate or in an array format on a substrate. Disclosed are detection assays employing sensor biomolecules that do not comprise a fluorophore that can exchange energy with the cationic multichromophore. Disclosed are biological assays in which energy is transferred between one or more of the multichromophore, a label on the target biomolecule, a label on the sensor biomolecule, and/or a fluorescent dye specific for a polynucleotide, in all permutations.Type: GrantFiled: December 24, 2012Date of Patent: June 24, 2014Assignee: The Regents of the University of CaliforniaInventors: Guillermo C.
