Two peripherally octasubstituted zincphthalocyanines (ZnPcs) bearing six alkoxy residues and two adjacent carboxylic acid anchoring groups were synthesized in order to assess the benefits deriving from the insertion of fluorocarbon domains at the periphery of ZnPc photosensitizers to be used in dye-sensitized solar cells (DSSCs). To this end the alkoxy substituents were terminated with tert-butoxy
