  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   ****–LUMO gap as a function of compound length. Long-range   three-dimensional πoverlap occurs in the   iBu3Si-substituted pentacene dimer (see   figure; n=2).
