Two D-π-A dyes, one with a strong electron withdrawing cyanoacrylic acid <b>DPP 20</b> and one with a weak acceptor carboxylic acid <b>DPP 21</b> have been synthesized and characterized for their application in dye-sensitized solar cells. This allows us to understand the role of electron withdrawing strength of the acceptor anchoring groups on the optoelectronic properties of chromophoric π spacer molecules, e.g., the diketopyrrolopyrrole (DPP) moiety. The low energy absorption maxima of DPP 20 is red-shifted by only 7 nm compared to DPP 21, implying a minimal role for the strong acceptor in the light harvesting properties of colored π spacer molecules. Because of this small red shift, <i>J</i><sub>SC</sub> of DPP 20 is marginally higher th...
