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.

reaction, purified according to a very simple procedure, and isolated in 84% yield. The efficient synthesis of two new methylated quinque- and sexithiophenes displaying liquidcrystalline properties is reported. A new microwave-assisted methodology for the conversion of aldehyde-terminated quinque- and sexithiophenes into the corresponding cyano derivatives is also described. The use of microwaves was
