The synthesis and characterization of a series [1]benzothieno[3,2-b][1]benzothiophene (BTBT) molecules disubstituted by hydroxy aliphatic chains in positions 2 7 (BTBT-CnOH), where the intralayer molecular stacking alternates between classical an inverted herringbone mode as function whether alkyl sides have even or odd number carbon atoms are reported. This odd–even effect does not only affect...

Conjugated polymers encompassing delocalized π-electrons in their backbones exhibit high photoabsorption and efficient charge carrier transport through the intermolecular π-π stacking suitable for organic photovoltaics (OPV). By contrast, small molecules such as [1]benzothieno[3,2-b][1]benzothiophene (BTBT) derivatives, which demonstrates field-effect transistor hole mobilities owing to 2-dimen...

The molecule 2-decyl-7-phenyl[1]benzothieno[3,2-b][1]benzothiophene has gained a lot of attention since high charge carrier mobility was observed in thin film transistors. Its thermotropic liquid crystalline states may play an important role the formation smectic A and crystal E phase (SmE) are claimed to be pre-stages final bulk structure. To understand diversity, structural characterisation s...

A flexible optoelectronic neural transistor (OENT) that consists of a one-step spin-coated tri-blend film composed 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT), poly(3-hexylthiophene-2,5-diyl) (P3HT), and poly(methyl methacrylate) (PMMA) is demonstrated. The C8-BTBT P3HT phases in the partially segregate into distinct domains, which combine to provide broadband spectrum sensing, ...

In this study, we have combined structural comparisons and the rugosity model to investigate experimental predicted crystal structures from previous results of a structure prediction study on group three rigid, planar small molecules, 2-methyl-, 3-methyl-, 2,3-dimethyl-benzo[b]thiophene 1,1-dioxide. The provided some insights into possibility that pairs predictions, close in energy, might be re...

Directional crystallization from the melt has been used as a tool to grow parallel crystalline stripes of p- and n-type molecular semiconductors. To start, phase behavior 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT-C8): tetracyanoquinodimethane (TCNQ) blends (molar ratio 20:1 1:1) investigated by variable-temperature X-ray diffraction, differential scanning calorimetry, polarized...

The intermediate di-[EMIM]Cl was synthesized from methyl imidazole and 1,4-dichlorobutane then reacted with cobalt chloride at 105 °C to prepare a bi-[EMIM]CoCl3 ionic liquid catalyst. di-[EMIM]CoCl3 catalyst coupled oxone remove sulfur-containing organics in octane. characterized by HNMR, FTIR, TG, SEM–EDS. dibenzothiophene (DBT) dissolved octane model oil an initial sulfur content of 500 ppm....
