A Rhenium Tricarbonyl 4′‐Oxo‐terpy Trimer as a Luminescent Molecular Vessel with a Removable Silver Stopper

Abstract

Shining metal cups: A luminescent tube of triangular cross-section and stoppered by a silver ion (see picture: Re yellow, N blue, O red) is formed in two steps from commercial materials. The silver ion can be removed to give a tube, and both species are potential hosts for small ions and molecules; a change in luminescence is triggered by the encapsulation of silver.
