Effects of chalcogen atom variation in chalcogenadiazole fused indolo[2,3-: A] carbazoles

A series of chalcogenadiazole fused indolo[2,3-a]carbazoles 1-3 were prepared, wherein a chalcogen atom was varied from oxygen (O) to sulphur (S) to selenium (Se) in the chalcogenadiazole unit. A Cadogan ring closing reaction was used as the key synthetic step for the preparation of 1-3. The chalcogen alteration (O, S and Se) led to a significant change in the structural, optical and electrochemical properties of 1-3, indicating a subsequent change in their HOMO-LUMO energy levels. Density functional theory (DFT) calculations were performed to further support the experimentally observed trend.

Synthesis and properties of benzobis(thiadiazole)s with nonclassical π-electron ring systems

Benzo[1,2-c:4,5-c']bis([1,2,5]thiadiazole) containing a hypervalent sulfur atom has a low LUMO energy. The aryl derivatives were synthesized using a Stille coupling reaction. The selenadiazole analogues were also prepared. The electron accepting properties of these nonclassical heterocycles were shown by their high reduction potentials. Introduction of electron-donating groups into the electron-withdrawing heterocycles afforded novel donor-acceptor compounds. Their cyclic vollammograms showed that they are easily both oxidized and reduced. Some of them have the absorption maxima above 700 nm due to the small HOMO-LUMO separation. X-ray structure analysis of the diphenyl derivative revealed the formation of a tape-like network through short S···N contacts.
