AbstractSnO2 nanoparticles have been synthesized and used as electron transport material (ETM) in dye sensitized solar cells (DSSCs), featuring two peripherally substituted push-pull zinc phthalocyanines (ZnPcs) bearing electron donating diphenylamine substituents and carboxylic acid anchoring groups as light harvesters. These complexes were designed on the base of previous computational studies suggesting that the integration of secondary amines as donor groups in the structure of unsymmetrical ZnPcs might enhance photovoltaics performances of DSSCs. In the case of TiO2-based devices, this hypothesis has been recently questioned by experimental results. Herein we show that the same holds for SnO2, despite the optimal matching of the optoelectronic characteristics of the synthesized nanoparticles and diphenylamino-substituted ZnPcs, thus confirming that other parameters heavily affect the solar cells performances and should be carefully taken into account when designing materials for photovoltaic applications.

3[Formula: see text]-Carboxy-pyropheophorbides-[Formula: see text] possessing a variety of [Formula: see text]-substituted carbamoyl groups at the 17[Formula: see text]-position were prepared by modifying naturally occurring chlorophyll-[Formula: see text]. 3[Formula: see text]-Methoxycarbonyl-pyropheophorbide-[Formula: see text] was obtained via the protection of the 17[Formula: see text]-carboxy group with an allyl group, and amidated with various primary and secondary amines at the free 17-propionate residue, followed by the acidic hydrolysis of the methyl ester in the 3-substituent to give the desired pyropheophorbide-[Formula: see text] secondary and tertiary amides, respectively, bearing the trans-3[Formula: see text]-COOH. The synthetic pigments potentially usable for dye-sensitized solar cells gave almost the same optical properties in a solution.
