Control of Lanthanide Coordination Environment: Synthesis, Structure, and Oxygen-Sensitive Luminescence Properties of an Eight-Coordinate Tb(III) Complex
environment of the Tb3+ ion in oxygen-sensitive luminescent complexes can be successfully controlled through the size of alkyl substituents on ligands (RMeArOH)4cyclen} (R = tBu or Me; cyclen = 1,4,7,10-tetraazacyclododecane); a newly prepared eight-coordinate complex 1tBu shows higher oxygen sensitivity (KSV = 17 600) and lower luminescence quantum yield (Φ = 0.67 under N2) than those of the previously
This communication presents a new terbium(iii) complex that shows the highest luminescence quantum yield among the oxygen-sensitive lanthanide complexes.

A gadolinium(<scp>iii</scp>) complex that shows room-temperature phosphorescence in the crystalline state
This paper presents a gadolinium(III) complex that shows blue phosphorescence in the crystalline state at room temperature under air atmosphere; color of the crystals can be changed to pale-green from blue by doping of 1-naphthol.
