Electronic And Structural Properties

The synthesis of four N-functionalized bis[1]benzothieno[3,2-b:2′,3′-d]pyrroles (BBTPs) is reported in order to provide a more detailed characterization of these fused-ring units, as well as increase the scope of known BBTP units available for application to conjugated materials. The optical, electronic, and structural properties of the resulting BBTP units have been compared to the parent N-alkyl- and N-aryl-dithieno[3,2-b:2′,3′-d]pyrroles (DTPs), as well as their corresponding 2,6-diphenyl derivatives, in order to fully quantify the relative electronic effects resulting from benzannulation of the parent DTP building block. Such comparative analysis reveals that benzannulation results in a red-shifted absorbance, but to a lesser extent than simple phenyl-capping of the DTP. More surprising is that benzannulation results in stabilization of the BBTP HOMO, compared to the destabilization normally observed with extending the conjugation length of the backbone.

Potential Antimicrobial Activity

In this study, the synthesis and characterization of new thiazolo[3,2-b][1,2,4]triazol-6(5H)-ones 3-5 are described starting from 5-[4-(4-X-phenylsulfonyl)phenyl]-4H-1,2,4-triazole-3-thioles 2. The treatment of 1,2,4-triazole-3-thioles 2 with chloroacetic acid and substituted or non-substituted benzaldehydes in the presence of sodium acetate, acetic acid and acetic anhydride gave fused ring compounds 3-5. The structures of thiazolo-triazolones 3-5 have been elucidate by elemental analysis and IR, UV, 1H-NMR, 13C-NMR, MS spectra. Some of the newly synthesized products were tested for their antimicrobial effects.
