Synthèse et caractérisation de molécules en haltère à base de phtalocyanines pour l’élaboration de cellules solaires organiques

Abstract : This work reports a series of dumbbell-shaped molecules based on phthalocyanine with an electro-donating character, to be used in organic solar cells. More particularly, the molecules are fully-conjugated triads, made of two zinc phthalocyanine fragments separated by a rigid central dye of different nature (derivative of benzothiadiazole, isoindigo or diketopyrrolopyrrole). The synthesis of the materials was optimized by varying the type of the cross-coupling reactions. The properties of the molecules (absorption, energy levels, structure, charge transport and photovoltaic) were investigated as function of the nature of the central dye and the peripheral ramified chains on the phthalocyanine fragments.
