A large number of new liquid crystals incorporating the 2,5-disubstituted thiophene ring have been prepared and their mesomorphic behaviour studied in order to systematically investigate the correlation between the molecular structure and mesomorphism of thiophene derivatives with different shapes, polarisability and polarity. As a consequence of these investigations we have prepared a new class of liquid crystals incorporating a 2,5-disubstituted thiophene ring and a conjugated trans-carbon–carbon double bond in the terminal chain. These novel thiophene derivatives are the first liquid crystals incorporating a 2,5-disubstituted thiophene ring to exhibit a nematic phase at room temperature. This enables the flexoelectric coefficients of a bent-shaped molecule to be measured directly and at room temperature for the first time to the authors' knowledge. Many of these new thiophenes exhibit a high birefringence and a high nematic clearing point and are of potential
use as components of nematic mixtures in LCDs.

The present invention is directed to the provision of a liquid crystalline organic semiconductor material, which is highly stable under a film forming environment and, at the same time, can easily form a film, for example, by coating. The liquid crystalline organic semiconductor material comprises: a thiophene skeleton comprising 3 to 6 thiophenes linearly connected to each other; and an identical alkyl group having 1 to 20 carbon atoms located on both sides of the thiophene skeleton, wherein acetylene skeletons each have been introduced into between the thiophene skeleton and the alkyl group, or acetylene skeletons have been introduced symmetrically into the thiophene skeleton.

P2, respectively) which show that copolymers has good stability in the air and assured a higher open circuit voltage when it photovoltaic application. These copolymer were used as donor along with PC71BM and the BHJ polymersolarcellsbased on P1:PC71BM and P2:PC71BM processed with chloroform (CF) solvent showed over all PCE of 4.54% and 4.36%, respectively. Additionally, the PCE was improved up to
