摘要

Eight novel heterocyclic bridged phanes of the paraquat type were synthesized by a simple two-step procedure. Starting from furan bridged bis (4, 4′-bipyridinium) dication 2 and the corresponding bis (bromomethyl) arenes furanophanes of 4, 4′-bipyridine were obtained in moderate to high yields. In similar manner thiphenophane 9 was synthesized in low yield using dication 8 as precursor. The spectroscopic properties of furanophane 4 and ...
