Novel supramolecular liquid-crystalline complexes derived from 5-n-decyl-substituted thieno[3,2-b]thiophene-2- and thiophene-2-carboxylic acids
Abstract
A convenient route to thieno[3,2-b]thiophene-2-carboxyaldehyde (1) for the synthesis of new 5-n-decylthieno[3,2-b]thiophene-2-carboxylic acid (10) is described. A class of novel supramolecular liquid-crystalline complexes are formed starting from 10 or 5-n-decylthiophene-2-carboxylic acids and stilbazoles, through intermolecular hydrogen bonding.
