Investigation of the role of 1,3,4-oxadiazole on the spectroscopic, optical, and electrochemical properties of benzimidazolophanes

The synthesis of 1,3,4-oxadiazole (OXD)-based dicationic cyclophanes has been achieved via an N-alkylation route, and UV–vis spectra proved the absence of charge transfer interactions. Electrochemical studies showed interference of the OXD unit on the characteristic redox properties of dicationic benzimidazolophanes.
