hexafluorophosphate and column chromatography. On treating L3 with RuCl3, the homoleptic ruthenium complex [Ru(L3)2][PF6]2 was obtained. The synthesized metallo receptors contain oxa-aza crown or polyazacycloalkane moieties as recognition sites and [Ru(tpy)2]2+ cores as the signal-generating centre. The electronic spectra of the complexes are as expected for an Ru(tpy)22+ chromophore, with the main Ru[d(π)] tpy(π*)
