Switchable thiophene coordination in Ru (ii) bipyridyl phosphinoterthiophene complexes
Chemical communications, 2002•pubs.rsc.org
… In this communication, we describe the preparation of Ru(II) bipyridyl phosphinoterthiophene
complexes in which the terminal thiophene is S- or C-coordinated, as well as switching between
these modes. Previous studies have examined the use of complexed π-conjugated polymers
to electronically vary transition metal reactivity; modification of the electronic properties of Re
centres by oxidation of a … We have used phosphinoterthiophene ligands because they have
been previously demonstrated to strongly bind metal centres via the phosphine and to exhibit …

Switching between P,S- and P,C coordination modes of 3′-phosphinoterthiophene to Ru(II) results in substantial differences in the electronic spectra and cyclic voltammetry of these complexes.
