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

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

Crystallisation-enhanced bulk hole mobility in phenothiazine-based organic semiconductors
A series of three novel donor-acceptor systems based on C(3)-malononitrile-substituted phenothiazines was synthesised in good overall yields and their thermal, spectroscopic, and electrochemical properties were characterised. The compounds were prepared through a sequence of Ullmann-coupling, Vilsmeier-Haack formylation and Knoevenagel-condensation, followed by Suzuki-coupling reactions for int...
متن کاملNanotubes are High Mobility Semiconductors
The electron transport properties of a very long (20 micron) CVD-grown nanotube are reported. In this device the transport is dominated by intrinsic scattering processes at room temperature. The room temperature hole mobility is 20,000 cm/Vs, exceeding that of technologically-relevant semiconductors. The mobility increases with decreasing temperature, and is estimated to be greater than 180,000...
متن کاملTetracene dicarboxylic imide and its disulfide: synthesis of ambipolar organic semiconductors for organic photovoltaic cells.
We have designed and synthesized a new donor/acceptor-type tetracene derivative by the introduction of dicarboxylic imide and disulfide groups as electron-withdrawing and -donating units, respectively. The prepared compounds, tetracene dicarboxylic imide (TI) and its disulfide (TIDS) have high chemical and electrochemical stability as well as long-wavelength absorptions of up to 886 nm in the t...
متن کاملSelf-organized discotic liquid crystals for high-efficiency organic photovoltaics.
Self-organization of liquid crystalline and crystalline-conjugated materials has been used to create, directly from solution, thin films with structures optimized for use in photodiodes. The discotic liquid crystal hexa-peri-hexabenzocoronene was used in combination with a perylene dye to produce thin films with vertically segregated perylene and hexabenzocoronene, with large interfacial surfac...
