The complete molecule of the title compound, C20H32N2O6, is generated by crystallographic inversion symmetry. The two mutually trans nitro substituents are hence in fully eclipsed conformation and also twisted by 43.2 (2)° with respect to the phenyl

Lanthanide complexes of tetrapicolyl cyclen displayed remarkably high affinities for fluoride (log K≈5) in water, and were shown to form 1:1 complexes. The behaviour of these systems can be rationalised by changes to the magnitude of the crystal-fi

Cyanide ions are shown to interact with lanthanide complexes of phenacylDO3A derivatives in aqueous solution, giving rise to changes in the luminescence and NMR spectra. These changes are the consequence of cyanohydrin formation, which is favored by

A study of the anion-binding properties of three structurally related lanthanide complexes, which all contain chemically identical anion-binding motifs, has revealed dramatic differences in their anion affinity. These arise as a consequence of change

Binuclear lanthanide complexes consisting of two lanthanide binding domains in kinetically stable DO3A binding pockets linked by a 3-functionalized meta-xylyl bridge form stable 1:1 adducts with isophthalate and dinicotinate in water. The influence o

Sensitized luminescence from trivalent lanthanide ions relies on an appropriate energy match between the sensitizer’s excited state (triplet or singlet) and the lanthanide excited state manifold, and also an efficient mechanism of energy transfer b

Yb⋅DTMA forms a ternary complex with fluoride in aqueous solution by displacement of a bound solvent molecule from the lanthanide ion. [Yb⋅DTMA⋅F](2+) and [Yb⋅DTMA⋅OH2 ](3+) are in slow exchange on the relevant NMR timescale (

A europium complex derived from NP-(DO3A)2 exhibits pH-dependenteuropium-centred luminescence following excitation of the nitrophenolatechromophore. Such behaviour is not observed with an analogous mononuclear complex, suggesting coordination of both

The association between dinuclear lanthanide complexes and dicarboxylate guests has been studied to elucidate the factors that influence the self-assembly of these ternary structures. The self-assembly between α,α-bis(Eu·DO3A)-m-xylyl (H3DO3A = 1,
