摘要：

Mind the band gap: π-conjugated pentacene di-, tri-, and tetramers can be synthesized by using a versatile building block in Hay homocoupling as well as Cadiot-Chodkiewicz cross-coupling reactions. This modular approach allows the evaluation of solubility, stability, and the HOMO-LUMO gap as a function of compound length. Long-range three-dimensional π overlap occurs in the iBu3Si-substituted pentacene dimer (see figure; n=2). © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
