1% and 0.44 ± 0.01 ms for Tb(III) and for PyboxBr they were 35.8 ± 1.6% and 1.46 ± 0.03 ms for Eu(III) and 23.3 ± 1.3% and a double lifetime of 0.79 ± 0.05/0.07 ± 0.01 ms for Tb(III). A linearrelationship between the triplet level energies and the Hammett σ constants was found. Lifetime measurements in methanol as well as the NMR data in both methanol and acetonitrile indicate that all complexes are

A new complex of 4-thiophen-3-yl-pyridine-2,6-bis(oxazoline) with Eu(III) triflate has been isolated. This complex and its Tb(III) analogue are luminescent in the solid state. The complexes dissolve with partial retention of the solid-state structure in acetonitrile to yield highly luminescent solutions with quantum yields of 76.2 and 58.6% for red and green emission, respectively.
