  • ?-conjugated mono-, oligo- and polymeric compounds, and photovoltaic cells comprising them
    Patent number: 7973074
    Abstract: Monomeric, oligomeric or polymeric compound corresponding to the following formula (I): in which: A represents an optionally substituted polycyclic group, the said polycyclic group comprising at least one group capable of making possible the attachment of a chromophoric group, X1 and X2, which are identical or different, each independently represent a group of formula (II): in which: B and D, which are identical or different, each independently represent an aromatic carbon ring or an aromatic heterocycle which is optionally substituted. Use of the said compound in an optoelectronic device, such as a photovoltaic cell, a field-effect transistor or an electrochemical sensor. Photovoltaic cell comprising an active layer comprising an electron donor composed of the said compound.
