Resumen: We report two novel systems based on calix4]arene scaffolds with one or two D-p-A dyes for DSSCs which present good optical and photovoltaic properties as well as suitable electron lifetimes. The system (Cx-2-TPA) opens up the possibility to prepare more D-p-A branched dyes for increased light-current conversion efficiencies.
