There has been a renaissance in the interdisciplinary field of Molecular Magnetism since ~2000, due to discovery impressive properties and potential applications d- f-metal Single-Molecule Magnets (SMMs) Single-Ion (SIMs) or Monometallic Magnets. One consequences this an explosive growth synthetic molecular inorganic organometallic chemistry. In SMM SIM chemistry, organic ligands play decisive role, sometimes equally important that magnetic metal ion(s). bridging propagate strong...
A unique family of [LnLn′Ln] heterometallic complexes with high site selectivity are suitable platforms for 3-qubit operations, good quantum coherence attributes.
Facile access to site-selective hetero-lanthanide molecules will open new avenues in the search of novel photophysical phenomena based on Ln-to-Ln' energy transfer (ET). This challenge demands strategies segregate efficiently different Ln metal ions among positions a molecule. We report here one-step synthesis and structure pure [YbNdYb] (1) coordination complex featuring short Yb···Nd distances, ideal investigate potential distributive (i.e., from one donor two acceptors) intramolecular ET...
A pure heterometallic coordination complex featuring the [ErNdEr] at core has unveiled an unprecedented phenomenon of two simultaneous intramolecular energy transfer between Nd 3+ and Er .
The initial use of anils, i.e. bidentate Schiff bases derived from the condensation anilines with salicylaldehyde or its derivatives, in 4f-metal chemistry is described. 1 : reactions between Ln(NO3)3·xH2O (Ln = lanthanide) Y(NO3)3·6H2O and N-(5-bromosalicylidene)aniline (5BrsalanH) MeCN has provided access to complexes [Ln(NO3)3(5BrsalanH)2(H2O)]·MeCN Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb) [Y(NO3)3(5BrsalanH)2(H2O)]·MeCN, respectively, good yields. structures isomorphous Ln Pr(1·MeCN),...
The initial use of a tetradentate Schiff base (LH2) derived from the 2 : 1 condensation between 2-hydroxyacetophenone and cyclohexane-1,2-diamine in 4f-metal chemistry is described. reaction Ln(NO3)3·xH2O (Ln = lanthanoid or yttrium) LH2 MeOH/CH2Cl2 has provided access to isostructural complexes [Ln(NO3)3(L'H2)(MeOH)] moderate good yields. Surprisingly, products contain corresponding ligand L'H2 possessing six aliphatic -CH2- groups instead -CH-(CH2)4-CH- unit cyclohexane ring, i.e. an...
The reactions of hydrated lanthanide(III) [Ln(III)] nitrates and salicylideneaniline (salanH) have provided access to two families mononuclear complexes depending on the reaction solvent used. In MeCN, products are [Ln(NO3)3(salanH)2(H2O)]·MeCN, and, in MeOH, [Ln(NO3)3(salanH)2(MeOH)]·(salanH). within each family proven be isomorphous. structures [Ln(NO3)3(salanH)2(H2O)]·MeCN (Ln = Eu, 4·MeCN_Eu, Ln Dy, 7·MeCN_Dy; Yb, 10·MeCN_Yb) [Ln(NO3)3(salanH)2(MeOH)]·(salanH) Tb, 17_Tb; 18_Dy) been...
The controlled and reproducible molecular assemblies incorporating lanthanide centers represents a crucial step in driving forward up- down-conversion processes. This challenge calls for the development of strategies to facilitate efficient in-situ segregation different Ln metal ions into distinct positions within molecule. unique family pure [LnLn′Ln] heterometallic coordination compounds previously developed by us an ideal platform studying desired Ln-to-Ln′ energy transfer (ET).
