Construction and characterizations of new perylenediimide based molecular assemblies derived from nitro or amino bay-substituted derivatives

Abstract : Among the powerful organic electron acceptors are those based on perylenediimide derivatives. Their rigid planar backbone and extended π-conjugation with outstanding optical and electronic properties, chemical and thermal stabilities allowed them to be potentially useful as n-type materials in applications such as organic photovoltaic cells (OPVs).This dissertation describes the study of perylenediimide reactivity at the bay region for the synthesis and characterizations of new original acceptor systems. Some of them were applied in organic solar cells. In the first part of this thesis, an alternative procedure to conventional Suzuki-Miyaura coupling method was developed for the synthesis of PDI derivatives starting from mono-nitro PDI. From this was targeted the construction of PDI-C60dyad.In the second part, synthesis and characterizations of PDI dimer and its application in organic solar cells are discussed. In the last part, investigations on the reactivity of mono-amino PDI are described via the chemistry of the diazonium salt or through the synthesis of PDI-based azacoronene dyads. Preliminary studies of some of these acceptors in organic solar cells are also presented
