Abstract

Abstract : Simply "migrating" the aromatic sextet of cata -condensed 2D PAH with the same number of fused benzene rings affords novel organic semiconductors with different properties. Abstract : We report a facile synthesis of novel angularly fused bistetracene derivatives where two tetracene skeletons are cata -annulated at three benzene rings. Compared with previously described examples, our bistetracenes exhibit a narrower HOMO–LUMO gap but still exhibit high stability. Attempted synthesis of di-substituted bistetracene (BT-2TIPS) also led to unexpected triple (BT-3TIPS) and four-fold (BT-4TIPS) alkylsilylethynyl substitution. The photophysical, electrochemical and optical properties as well as the solid-state structure of these three bistetracene analogues are investigated. A charge carrier mobility up to 0.42 cm 2 V −1 s −1 was determined based on field effect transistors.
