Abstract

This paper presents the first dysprosium(iii) complex, [{(^MeMeArO)₃tacn}Dy^III(THF)] (1^Dy), that shows oxygen-sensitive luminescence. The synthesis, structure and oxygen-sensitive luminescence properties of 1^Dy are reported (Φ = 0.050 and τ = 17.7 μs under N₂, Φ = 0.011 and τ = 4.1 μs under O₂ 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, [{(^MeMeArO)₃tacn}Gd^III(THF)].
