The temperature dependence of the emission lifetime of the series of complexes Ru(bpy),(4,4'-dpb): ? (bpy = 2,2'-bipyridine, 4,4'-dpb = 4,4'-diphenyL2,2'-bipyridine) has been studied in propionitrile/butyronitrile (4:5 u/u) solutions in the range 90-293 K. The obtained photophysical parameters show
## Abstract [2]Rotaxanes based on the 1,2‐bis(pyridinium)ethane⊂[24]crown‐8 ether motif were prepared that contain a terminal terpyridine group for coordination to a transition‐metal ion. These rotaxane ligands were utilized in the preparation of a series of heteroleptic [Ru(terpy)(terpy–rotaxane)]
