Butterfly-like Shape Liquid Crystals Based Fused-Thiophene as Unidimensional Ambipolar Organic Semiconductors with High Mobility

Mesomorphous butterfly-like shape molecules based on benzodithiophene, benzodithiophene-4,8-dione and cyclopentadithiophen-4-one core moieties were efficiently synthesized by the Suzuki-Miyaura coupling and Scholl oxidative cyclo-dehydrogenation reactions’ tandem. Most of the butterfly molecules spontaneously self-organize into columnar hexagonal mesophase. The electron-deficient systems possess strong solvent-gelling ability but are not luminescent, whereas the electron-rich terms do not form gels but strongly emit light between 400 and 600 nm. The charge carrier mobility was also measured by time-of-flight transient photocurrent technique in the mesophases for some of the compounds. They display hole-transport performances with positive charge mobility in the 10?3 cm?2 V?1 s?1 range, consistent with the high degree of ordering and stability of the columnar superstructures. In particular, the mesogen with a benzodithiophen-4,8-dione core shows ambipolar charge carrier transport with both high electron (μe=6.6×10?3 cm?2 V?1 s?1) and hole (μh=4.5×10?3 cm?2 V?1 s?1) mobility values.

New discotic mesogens based on triphenylene-fused triazatruxenes: Synthesis, physical properties, and self-assembly

A new type of discotic mesogen based on triphenylene-fused triazatruxenes was prepared by microwave-assisted 6-fold Suzuki coupling reactions from hexabromotriazatruxene, followed by FeCl3-mediated oxidative cyclodehydrogenation. These disklike molecules showed extended π-conjugation, compared with the triphenylene and triazatruxene themselves. More importantly, they possess desirable HOMO energy levels, which allow efficient charge injection from electrodes such as gold electrodes. Their thermal behavior and self-assembly were studied by different techniques such as thermogravimetric analysis, differential scanning calorimetry, polarizing optical microscopy, and variable-temperature X-ray diffraction. These new discotic mesogens have very good thermal stability and show thermotropic liquid crystalline behavior. Ordered columnar liquid crystalline phase and crystalline phase were observed in both compounds with tunable phase transition temperatures and mesophase widths. The charge carrier mobilities of these extended triazatruxene samples were determined using the space-charge limited-current (SCLC) technique and high hole mobilities of 0.03 and 0.8 cm2 V-1 s-1) were obtained for TP-TATC6 and TP-TATC12, respectively. Interestingly, the long-aliphatic-chain-substituted TP-TATC12 can gelate several nonpolar hydrocarbon solvents or polar aliphatic alcohol and ester solvents, because of strong intermolecular interactions. All these properties qualify this new type of discotic liquid crystals as potential hole transporting materials for electronic devices such as field-effect transistors, light-emitting diodes, and solar cells.
