Abstract :

Dumbbell-shaped molecules containing large pi-stacking platforms at the molecular termini were found to be of high interest for solution-processable low band gap donor molecules for efficient bulk heterojunction (BHJ) solar cell. Different types of pi-stacking platforms were already reported (e.g., Pyrene, Perylenedimide, Triazatruxene) leading to molecular selfassemblies, ultimately leading to good photovoltaic performances. Metal phthalocyanines are large and functionalizable aromatic platforms which constitute promising pi-staking units in the design of novel molecules for organic photovoltaic applications. In this line, we have developed a series of dumbbell-shaped molecules, containing Zinc Phthalocyanine as the terminal pi-staking platforms and a Dithieno benzothienothiophene derivative as the central connecting moiety. In this presentation we will describe the synthesis and characterization of the molecules. It will be shown in particular, that the chains substituted to the Phthalocyanine platforms is of high importance, as the chain density controls the molecular organization and the nature of the linking groups (OR, SR, SO2R) can be used to control the absorption and energy levels of the molecules.
