This paper presents the first dysprosium(III) complex, [{((ArO)-Ar-MeMe)(3)tacn}Dy-III(THF)] (1(Dy)), that shows oxygen-sensitive luminescence. The synthesis, structure and oxygen-sensitive luminescence properties of 1(Dy) are reported (Phi = 0.050 and tau = 17.7 mu s under N-2, Phi = 0.011 and tau = 4.1 mu s under O-2 and K-SV = 305 M-1 in THF; K-SV = 0.0077%(-1) in polystyrene film). The oxygen sensitive mechanism of 1(Dy) is discussed based on the photophysical properties of the corresponding gadolinium(III) complex, [{((ArO)-Ar-MeMe)(3)tacn} Gd-III(THF)].
