ABSTRACT:
An molecular complex is provided which includes a linear polymer associated with a cyclic molecule to form a rotaxane of the general formula, ##STR1## where R.sub.1 and R.sub.2 are blocking end groups of size and character sufficient to prevent dethreading of the rotaxane and said R.sub.1 and R.sub.2 the same or different;
where the cyclic molecule comprises a cyclic skeleton and at least one A functional group, said functional group attached to the cyclic skeleton;
where A is selected from the group consisting of polymerizable functional groups, cation complexing groups, anion complexing groups and ionic species; and
wherein at least one of R.sub.1, R.sub.2 and A are selected from the group consisting of cation complexing groups, anion complexing groups and ionic species.
The molecular complex may used in an electrolyte.
