title: Color tuning in new metal-free organic sensitizers (Bodipys) for dye-sensitized solar cells.
abstract: Fun in the sun! A strategy has been devised for functionalizing and solubilizing boron dipyrromethene (Bodipy) dyes at the central boron atom and changing the color by increasing delocalization on the central core. This approach leads to the formation of stable B-C[triple bond]C and pyrrole--C=C linkages suitable for use in TiO(2)-sensitized devices (see figure).
