Molecular design of benzothienobenzothiophene-cored columnar mesogens: Facile synthesis, mesomorphism, and charge carrier mobility

Benzothienobenzothiophene (BTBT) liquid-crystalline semiconductors are arousing a lot of interest due to their long-range ordered, self-organizational abilities and high-charge carrier transport properties. In this work, we report the design and the straightforward synthesis of a homologous series of compounds containing the BTBT substructure by the successive Suzuki cross-coupling and FeCl3 oxidative Scholl cyclodehydrogenation reaction. Target π-conjugated aromatic, H-shaped sanidic mesogens self-organize into a classical hexagonal columnar mesophase over wide temperature ranges as deduced from polarized optical microscopy (POM), differential scanning calorimetry (DSC), and small-angle X-ray scattering (SAXS) investigations. UV/Vis absorption and photoluminescence spectra, measured in both solution and films, revealed strong photoluminescence with high quantum yields. The charge carrier mobility measured by the time-of-flight (TOF) technique showed a balanced ambipolar hole and electron mobility in the range of 10-3 cm2 V-1 s-1 between 100 and 230 °C in the mesophase. These BTBT-based columnar liquid crystals may represent attractive candidates to be incorporated within one-dimensional organic optoelectronic devices.

Synthesis of extended triphenylenes by palladium-catalyzed [2+2+2] cycloaddition of triphenylynes

The synthesis of orttho-(trimethylsilyl)triphenylenyl triflates 7 is described. Fluoride-induced decomposition of these triflates leads to the generation of didehydrotriphenylenes (triphenylynes). 6. These arynes undergo [4+2] cycloadditions with dienes to afford the corresponding Diels-Alder adducts or palladium-catalyzed formal [2+2+2] cycloadditions to afford extended triphenylenes.
