摘要：
A kinetic template effect directs selection in competitive self‐assembly of tetracationic cyclophanes (represented by a circle) containing meta‐ or para‐linked 4,4′‐bipyridinium and/or bis(4‐pyridinium)ethylene units in the presence of competing crown ether templates (represented by a square or a triangle). The cyclophane fragments first couple covalently to form an intermediate (represented by an arc), and then the molecular recognition event strings the crown ether before the rate‐determining second covalent bond formation closes the ring.
