AbstractWe report a new complex Eu(tta)(3)center dot bpt (tta = thenoyltrifluoroacetonate; bpt = 2-(N, N-di-ethylanilin-4-yl)-4,6-bis(pyrazol-1-yl)-1,3,5-triazine) with excellent long-wavelength sensitized luminescent properties, in which four hydrogen atoms replace the methyl groups at the 3,3'- and 5,5'-positions of the pyrazolyl rings in a previously reported complex Eu(tta)(3)center dot dpbt. Upon visible-light excitation (lambda(ex) = 410 nm) at 295 K, the quantum yield (Phi(Ln)(L)) of Eu(3+) luminescence of Eu(tta)(3)center dot bpt is higher by 23% than that of Eu(tta)(3)center dot dpbt. Different from the case of Eu(tta)(3)center dot dpbt, Phi(Ln)(L) of Eu(tta)(3)center dot bpt increases linearly with the decrease in temperature. Because of the different coordination environments around Eu(3+) ion, the. ne structure of the hypersensitive (5)D(0)->(7)F(2) emission band of Eu(tta)(3)center dot bpt is quite different from that of Eu(tta)(3)center dot dpbt, with the strongest emission line locating at 620 nm rather than 613 nm where the strongest emission line of Eu(tta)(3)center dot dpbt appears. The excitation window of Eu(tta)(3)center dot bpt is much broader than that of Eu(tta)(3)center dot dpbt with a red edge extending up to 450 nm in a dilute toluene soluton (1.0 x 10(-5) M) and 500 nm in a toluene solution (1.0 x 10(-2) M). Eu(tta)(3)center dot bpt also exhibits excellent two-photon-excitation luminescent properties.
