Abstract: Photoactive polymers comprising first and second co-monomer repeat units, the first co-monomer repeat unit comprising a moiety selected from the group consisting of an alkylthieno[3,4-c]pyrrole-4,6-dione moiety and a 1,3-dithiophene-5-alkylthieno[3,4-c]pyrrole-4,6-dione moiety, and the second co-monomer repeat unit comprising a moiety selected from the group consisting of a 4,4?-dialkyl-dithieno[3,2-b:2?3?-d]silole moiety, an ethylene moiety, a thiophene moiety, an N-alkylcarbazole moiety, an N-(1-alkyl)dithieno[3,2-b:2?3?-d]pyrrole moiety and a 4,8-dialkyloxylbenzo[1,2-b:3,4-b]dithiophene moiety are described herein. These polymers are suitable for use in photovoltaic cells and field effect transistors.

Abstract: Methods and tools (e.g., kits, articles of manufacturing, support and arrays) for the solid-phase detection of a target molecule using a cationic polymer and nucleic acid probe complex is provided herewith. These methods and tools allows for the reagentless, ultrasensitive and specific detection of nucleic acids, proteins and other molecules of interest and are based on a labeled complex made of specific capture probes and a polythiophene derivative.
