Abstract
We now report the synthesis of phophonium- and borate-bridged stilbene via intramolecular double cyclization from boryl- and phosphanyl-substituted diphenylacetylene derivatives. This cyclization is applicable to the synthesis of distyrylbenzene derivatives and thiophene-fused derivative. The obtained zwitterionic ladder compounds show totally different photophysical and electrochemical properties from those of the known ladder oligo(p-phenylenevinylene)s.
