Abstract

A [Ru(bpy)₃]²⁺ stopped “V” type guest molecule competitively prefers to thread into the cavity of cucurbit[7]uril to form a pseudo[2]rotaxane-like supramolecule because of the large binding constant between them rather than embedding into β-cyclodextrin in a system containing these three components.
