✦ Synopsis

The novel tridentate 2,2':6',2''-terpyridine ligand (1) in which the metalbinding domain is directly attached to a methanofullerene C 60 unit was incorporated into ruthenium-based diads and triads that may undergo photoinduced charge separation. In this paper, the new complexes are compared with more flexible analogues in which the C 60 fragment is separated from the metal-binding domain by a flexible spacer. Both 1 H NMR spectroscopic and cyclic voltammetric studies reveal significant interactions between the fullerene substituent and the metal centre when they are spatially close.

## 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)]
