“Cymothoe sangaris”: An Extremely Stable and Highly Luminescent 1,2-Hydroxypyridinonate Chelate of Eu(III)
摘要:
The synthesis, structure, and characterization of a new class of luminescent agents based on the 1,2-hydroxypyridinone chelator are reported. The prototype complex, [Eu(5LIO-1,2-HOPO)2]-, demonstrates superb aqueous stability [pEu = 18.64(10)] and is highly emissive [Phit = 0.21(3)], emitting almost pure "red" light (lambdaem = 612 nm). The crystal structure reveals a coordination geometry reminiscent of a "butterfly", hence the soubriquet of "Cymothoe sangaris" to identify with the unique species of red butterfly found only in Central Africa.

The electronic and magneticproperties of a set of mononuclear terbium(III) and dysprosium(III) complexes with two tetradentate 1‐hydroxy‐pyridin‐2‐one (1,2‐HOPO) ligands are reported. Two primary coordination geometries are observed, depending on the length of the linker between the 1,2‐HOPO donor moieties and the resulting arrangements of the linker. Fine details of the magnetic circular dichroism

photophysical properties of several trivalent lanthanidecomplexes formed from two differing bis-bidentate ligands incorporating either alkyl or alkyl ether linkages and featuring the 1-hydroxy-2-pyridinone (1,2-HOPO) chelate group in complex with Eu(III), Sm(III), and Gd(III) are reported. The Eu(III) complexes are among some of the best examples, pairing highly efficient emission (Phi tot (Eu) approximately
