A luminescent [Pd4Ru8](24+) supramolecular cage
Résumé
A phosphorescent cage of the form [Pd4Ru8](24+) is reported. The cage was formed using the metalloligand [Ru(dtbubpy)(2)(qpy)](2+), where qpy = 4,4': 2',2 `': 4 `',4'''-quaterpyridine and dtbubpy = 4,4'-di-tert-butyl-2,2'-bipyridine. The cage has been characterised by NMR, ESI-MS, TEM and X-ray diffraction analyses and its emission properties elucidated by steady-state and time-resolved emission spectroscopy.
