摘要

As an extension of our studies dealing with reversible redox systems, six tetraquaternary salts have been synthesized. These compounds contain two 4, 4'-bipyridinium units which are connected by either one or two rigid bridges. The single bridged systems (o-, m-3, p-3) contain one o-, m-or p-xylylene bridge. The double bridged systems (o, o-4, o, m-4 and m, m- 4) contain two xylylene bridges and represent a new class of cyclophanes. A new and ...
