      Abstract:

      Functionalization of   pentacene at the 6- and 13-positions affords versatile building   blocks for oligomer and polymer formation. Di- and trimeric   materials are synthesized using unsymmetrical building block 18,   while symmetrical diol monomer 17 allows for the synthesis of   polymers. The materials reported herein are soluble in common   organic solvents and air-stable. UV–vis and fluorescence   spectroscopic properties have been investigated. Solid-state   X-ray crystallography of building blocks 17 and 19 shows that   these derivatives can π-stack with significant acene face-to-face   interactions with spacing of less than 3.5 Å.
