The template effects exerted by compounds 3, 5, 6, and 8 in the ring closure reaction of the trication 13+ to yield the [2]pseudorotaxanes 154+ and 174+ and the [2]rotaxanes 184+ and 204+ have been quantitatively evaluated in acetonitrile at 62 °C by UV/vis spectrophotometry. The rate of ring closure of the trication 13+ largely increases in the presence of the templates up to a maximum of ca. 200
