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 buildingblocks for the synthesis of electron-deficient oligopyrroles. The latter application is demonstrated through the development of π-extended porphyrins containing
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.

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

reaction offers high yields of propeller‐shaped targets, even for electron‐deficient precursors, and shows electrophile‐dependent stereoselectivity, with N‐bromosuccinimide and dibromine yielding, respectively D6‐ and C2‐symmetric products. The propeller azacoronenes are chiral and can be separated into configurationallystableenantiomers. In addition to providing steric bulk, peripheral functionalization
