11-Ring heterocyclic diimides were synthesized and found to be planar and to exhibit a slipped face-to-face πstacking. Variation of the substituents tunes the electronic structure and properties. In n-channel organic field-effect transistors, the new organic semiconductors have a high electron mobility. When they were used as acceptor material in polymer solar cells, a power conversion efficiency of 1.8 % was obtained. Copyright

A family of bandgap-tunable pyrroles structurally related to rylene dyes was computationally designed and prepared using robust, easily scalable chemistry. These pyrroles show highly variable fluorescence properties and can be used as building blocks for the synthesis of electron-deficient oligopyrroles. The latter application is demonstrated through the development of π-extended porphyrins containing naphthalenediamide or naphthalenediimide units. These new macrocycles exhibit simultaneously tunable visible and near-IR absorptions, an ability to accept up to 8 electrons via electrochemical reduction, and high internal molecular free volumes. When chemically reduced under inert conditions, the most electron-deficient of these macrocycles revealed reversible formation of eight charged states, characterized by remarkably red-shifted optical absorptions, extending beyond 2200 nm. Such features make these oligopyrroles of interest as functional chromophores, charge-storage materials, and tectons for crystal engineering.

A novel naphthalimide derivative endowed with a diketone functionality has been synthesized and used to develop a family of highly symmetric, flat, n-type semiconducting naphthalimide-based pyrazinacenes. By changing the symmetry of these compounds and the number of naphthalimide constituents, fine tuning of their electrochemical, photophysical, and morphological properties is achieved.

Page/Page column 39; 40, (2014/03/25)
Novel acenaphthylene imide-derived semiconductor materials, including small molecule compounds, polymers and oligomers. Also provided are methods for making the novel semiconductor materials and the use of the novel semiconducting materials in electronic or optoelectronic device. In some embodiments, the novel semiconducting materials are used as n-channel component in organic field-effect transistors as well as complementary electronic circuits including inverters. High mobility can be achieved.

supporting information; experimental part, p. 1022 - 1026 (2009/07/19)
The synthesis of two complementary molecular moulds is described. These molecules comprise a polyaromatic central part and four lateral bulky tert-butylphenyl or di-tertbutylphenyl groups so that when they are deposited onto a surface, a cavity prone to metallic moulding is created.
