    Abstract

    We demonstrated versatile hydrogen-bonded assemblies of a twisted πsystem with newly synthesized tetra[3,4]thienylene tetracarboxylic acid ThTCA. Due to its twisted saddle-shaped central πaromatic unit with an anisotropic arrangement of carboxyl units, a variety of dimensional solvate molecular crystals could be obtained, in contrast to typical aromatic carboxylic acid derivatives with low-dimensional assemblies. The versatile molecular assemblies could be converged to ThTCAdesol by desolvation with a simple annealing technique. ThTCAdesol showed selective solvent sorption behavior, which was governed by the solvent association energy and saturated vapor pressure. Especially, ThTCAdesol showed the selective sorption of EtOH, among primary alcohols.
