E. Cordova et al., NOVEL ROTAXANES BASED ON THE INCLUSION COMPLEXATION OF BIPHENYL GUESTS BY CYCLOBIS(PARAQUAT-P-PHENYLENE), Journal of organic chemistry, 58(24), 1993, pp. 6550-6552
The finding that benzidine and 4,4'-biphenol form stable inclusion com
plexes in acetonitrile with the previously reported receptor cyclobis(
paraquat-p-phenylene) was used to self-assemble novel redox-active rot
axanes based on the interactions that stabilize these inclusion comple
xes.
