摘要：

The synthesis, characterization, and field-effect transistor (FET) properties of new alkylated indolo [3,2-b] carbazole (ICz) based materials are reported. Dialkyl substitution at the 2,8-positions of the ICz core structure do not affect strong N-H- at interactions, thus favoring a herringbone packing motif. OFET devices fabricated by compounds of this substitution pattern displayed a charge carrier mobility of similar to 10(-2) cm(2) V s(-1). These interactions are suppressed when introducing substituents at the 5,11-positions, resulting in greatly enhanced solubility. A solution processable ICz derivative was finally used in a newly developed pneumatic printing setup to yield a crystalline film with aligned crystals along the printing direction.
