New tetrazole-fused π-conjugated molecules were prepared from dibromobenzonitriles by repeated regioselective Sonogashira-Hagihara cross-coupling with acetylenes and intramolecular nucleophilic cyclizations. The conjugated tetracyclic compounds exhibited fluorescence with lifetimes of nanosecond order. From TD-DFT calculations, excited state wavefunctions of compounds indicated that the HOMO-1→LUMO and HOMO→LUMO+1 mainly became the first excited state (S0→S1) to contribute significantly to light emission.

A novel and efficient route was established for the synthesis of a series of (Z)-5-(2-(heteroaryl-2-yl) and (Z)-5-(3-(heteroaryl-3-yl)-1-(phenyl)vinyl)-1H-tetrazoles (3a-g and 6a-f, respectively) from cyanostilbene analogs containing benzo[b]thiophene, be

A mild and mass-efficient procedure based on the one-pot diazotization-azidodediazoniation of aromatic amines is described. A wide range of aryl azides are obtained in moderate to high yields by using tributyltin azide as an effective and reusable azide source in the presence of p-toluenesulfonic acid at room temperature. The method was also successfully applied employing an insoluble polymer-supported organotin azide.
