Abstract

The template effect of 1,5-Bis[2-(2-triisopropyloxyethoxy)ethoxy]naphthalene (5) on the ring closure reaction of 2-(4-Bromomethylbenzyl)-7-[4-(2,7-diazapyrenyl)-methylbenzyl]-2,7-diazapyrenium (3), to give the corresponding [2]rotaxane (7), has been quantitatively evaluated. The results are compared to those relative to the self-assembly of [2]rotaxane (8), and [2]pseudorotaxanes (9) and (10).
