A new class of benzopyrene-based semiconducting molecules is prepared and characterized. A four-step protocol involving Suzuki coupling and aromatic dehydrogenation reactions renders the new unsymmetrical framework. Introduction of various substituents at the dibenzopyrene framework modulates mainly the optoelectronic properties rather than the packing motif. Single-crystal field-effect transistors fabricated from these materials show a mobility ranging from 0.7 to 3.2 cm2/(V s). The highest mobility, 3.2 cm2/(V s), with an on/off ratio of 104-105 was achieved for 11-methoxy-8-(4-methoxyphenyl)dibenzo[a,e]pyrene.

Dual activation of both C-I and vicinal C-H bonds of diaryliodonium salts allowing for diarylation is a subject of rapid construction of π-extended frameworks. Here, we report palladium-catalyzed cascade of C8-arylation/intramolecular Friedel-Crafts acylation of α-naphthoic acids in the synthesis of benzanthrone derivatives. The step-economical protocol tolerates various substrates, which resulted in a potential molecular library for developing functional polycyclic scaffolds. The approach relies on the synergistic action of strong acid with palladium catalysts to form two bonds in a one-pot procedure.
