  • Pyrrolopyrrole derivatives, their manufacture and use
    Patent number: 9018397
    Abstract: The present invention relates to compounds of the formula I wherein the substituents are as defined in claim 1, and their use as organic semiconductor in organic devices, like diodes, organic field effect transistors and/or a solar cells. The compounds of the formula I have excellent solubility in organic solvents. High efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when said compounds are used in semiconductor devices or organic photovoltaic (PV) devices (solar cells).
    Type: Grant
    Filed: February 26, 2013
    Date of Patent: April 28, 2015
    Assignee: BASF SE
    Inventors: Zhimin Hao, Beat Schmidhalter, Jean-Luc Budry, Margherita Fontana, Matheiu G. R. Turbiez, Frank Bienewald, Mathias Duggeli, Oliver Frederic Aebischer, Pascal Hayoz, Marta Fondrodona Turon

  • SUBSTITUTED OLIGO- OR POLYTHIOPHENES
    Publication number: 20110062426
    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: with a suitable lithium organic compound, preferably Li-alkyl or Li-alkylamide; b) optional exchange of lithium against another metal selected from Mg1 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 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.
