The overall quantum yields for phenanthridinium sensitised emission from a europium ion have been measured in H2O and D2O for a series of five structurally related, octadentate ligands in which the distance from the phenanthridinium chromophore to the Eu ion varies from 2.5 to ca. 8.2 Å. Overall quantum yields (pD2) range from 0.25 to 0.012 suggesting that the experimental distance for 50% efficiency of intramolecular energy transfer lies close to 5.5 Åfor this system. |
