Designed polynuclear lanthanide complexes for quantum information processing

Abstract

The design of dissymmetric organic ligands featuring combinations of 1,3-diketone and 2,6-diacetylpyridine coordination pockets has been exploited to produce dinuclear and trinuclear lanthanide-based coordination compounds. These molecules exhibit two or...

Using internal strain and mass to modulate Dy⋯Dy coupling and relaxation of magnetization in heterobimetallic metallofullerenes DyM2N@C80and Dy2MN@C80(M = Sc, Y, La, Lu)

“…22–31 Such a precise composition control in a virtually identical chemical environment is quite unique and rarely available for heterometallic systems in lanthanide chemistry. 32–38…”

“…[22][23][24][25][26][27][28][29][30][31] Such a precise composition control in a virtually identical chemical environment is quite unique and rarely available for heterometallic systems in lanthanide chemistry. [32][33][34][35][36][37][38] In this work, we employ the M′ x M″ 3−x N@C 80 platform to study the influence of the internal strain on the static and dynamic magnetic properties of Dy-containing nitride clusterfullerenes. The use of external stimuli to modulate the properties of single molecule magnets has attracted significant attention as it opens the way for multifunctional magnetic systems.…”

Metal-Based Linear Light Upconversion Implemented in Molecular Complexes: Challenges and Perspectives

“…Contrary to doped solids where the intermolecular energy transfer processes between the sensitizers and the activators are controlled by second-order kinetic rate laws, the association of the sensitizers and activators in the same molecular unit results in first-order kinetic rate laws that simplify physical modeling, prediction, design, and optimization. This molecular strategy opens remarkable perspectives when pure and well-organized (not statistically doped) heterometallic p–f, d–f, , and f–f′ − complexes are considered. If p–f pairs have been overexploited in coordination chemistry due to the early recognition of the benefit provided by the antenna effect for sensitizing trivalent lanthanides, the selective assembly of d–f systems is less common but still well-represented because the difference in the stereochemical preferences of well-identified d–f pairs can be exploited.…”
