Solution-processed small molecule transistors with low operating voltages and high grain-boundary anisotropy

We present a new soluble pentacene derivative with ethyl substitutions in the 1,13,14,22 backbone positions to modulate the solubility and film forming properties of this material compared to triisopropylsilylethynyl (TIPS) pentacene. This permits reproducible production of molecularly highly ordere...

Summary:We present a new soluble pentacene derivative with ethyl substitutions in the 1,13,14,22 backbone positions to modulate the solubility and film forming properties of this material compared to triisopropylsilylethynyl (TIPS) pentacene. This permits reproducible production of molecularly highly ordered structures that feature average transistor mobilities in excess of 1 cm super(2) V super(-1) s super(-1) depending on crystal orientation by careful selection of casting conditions.
