| titleOfInvention | Substituted oligo -or polythiophenes |
| abstract | A process for the preparation of a substituted 2, 2' -dithiophene is described, which process comprises the steps (a), (c) and optional steps (b) and (d): (a) reaction of a compound of the formula: wherein Hal stands for hydrogen or halogen, especially Br, R1 and R1' indepently are hydrogen or a substituent, n ranges from 0 to 6, preferably being 0; Y, if present, is substituted or unsubstituted phenylene, thiene, 1, 2-ethylene, or is 1,2-ethinylene; R2 and R2' indepently are hydrogen or are selected from C1-C25alkyl, C3-C12cycloalkyl, C4-C25aryl, C5-C25alkylaryl or C5-C25aralkyl, each of which is unsubstituted or substituted; with a suitable lithium organic compound, preferably Li-alkyl or Li-alkylamide; (b) optional exchange of lithium against another metal selected from Mg, Zn and Cu; (c) reaction of the metallated intermediate obtained in step (a) or (b) with a suitable electrophil, which is CO2 or an aldehyde (addition reaction), or a compound Y' -R17 or Y' -R18-Z (substitution reaction), where R17 and R18 are as defined in claim 1; and optionally d) modification of the product obtained in step (c), e.g. by introducing one or more conjugating moieties Y as defined above, ring closure between suitable monovalent residues R17, exchange or extension of functional groups or substituents such as addition to carbonyl or substitution of carbonyl in R17 or R18. The products, including or corresponding polymers, are excellent conducting materials, e.g. for application in organic field effect transistors, integrated circuits, thin film transistors, displays, RFID tags, electro- or photoluminescent devices, displays, photovoltaic or sensor devices, charge injection layers, Schottky diodes, memory devices, planarising layers, antistatics, conductive substrates or patterns, photoconductors, or electrophotographic applications or recording materials. |
