Stereogenic cyclic dimers based on 2,2′-biselenophene linked with [2.2]paracyclophane have been synthesized to investigate their chiroptical properties. Embedding selenophene led to the formation of intramolecular Se⋯π interactions between the two biselenophene strands. The resulting rigid cyclic system exhibits enhanced chiroptical properties when compared with its precursor. In addition, the electrochemical properties were also investigated.
