Oligothiophene-functionalized naphthalimides and perylene imides: design, synthesis and applications

Comprehensive UV–Vis and EPR spectroelectrochemical characterization of ambipolar azomethinenaphthaldiimides

“…The potential onset of the first step of reduction is almost the same for all investigated monomers and occurred at À0.90 V for Azndi 2 and Azndi 4, at À0.91 V for Azndi 3 and at À0.95 V for Azndi 1 (Table 1). This confirms lack of influence of kind of N-substitution on the reduction potential of investigated molecules, what is in agreement with the literature [54]. In contrast to reduction, oxidation process is irreversible for all investigated compounds.…”

N-type semiconducting perylene diimide based molecules for organic solar cells

“…PDI optoelectronic properties and supramolecular selfassembly characteristics can be finely tuned by chemical substitution of the perylene core. The PDI bay functionalization affords out-of-plane structures, which helps to reduce the π−π intermolecular interactions in the solid state [7,8]. In this paper we report the results obtained with two perylene diimides containing spirobifluorene moiety as core substituent: directly connected in PDI-SF or with bithiophene π-linkers in PDI-BSF (see Figure 1).…”

Azomethine naphthalene diimides as component of active layers in bulk heterojunction solar cells

“…Among the currently investigated classes of materials to form acceptor building blocks, naphthalene diimide (NDI) have aroused a lot of attention due to its valuable physical and electronic properties [9,17,19]. NDIs are usually investigated for organic thin film transistors (OTFTs) [13,20]. However, photovoltaic properties of NDIs are presented in a few articles where they were tested as acceptors for OPV [11,21,22].…”
