(Chemical Equation Presented) We report the synthesis of a series of crystalline acenedithiophenes with up to seven linearly fused rings and silylethynyl substituents. These functional groups are designed to both improve solubility and enhance cofacial interactions in the solid. We discuss the crystal packing of these materials, as well as their physical properties such as oxidation potential, UV-vis absorption, fluorescence emission, and decomposition pathways.

Benzo[b]thiophene-5,6-dicarboxaldehyde reacts with dibenzyl ketone, thiodiacetic acid dimethyl ester, hydrazine, p-toluidine, p-aminoacetophenone and nitromethane to give the corresponding seven, six and five-membered rings condensed to benzo[b]thiophene. Reaction ofbenzo[b]thiophene-5,6- dicarboxaldehyde with p-toluidine in the presence of 2-mercaptoethanol gives highly fluorescent compounds. Also, benzo[b]thiophene-5,6-dicarboxaldehyde was applied to fluorogenic reaction with some amino acids and the obtained data were compared with the reported data in the case of o-phthaldehyde. The synthesised compounds were characterised by their elemental analysis, IR, 1H NMR and mass spectrometry.
