Modulation of the magnetic and photophysical properties in 3d–4f and 4f–4f′ heterobimetallic complexes involving a tetrathiafulvalene-based ligand

Abstract

The reaction between the 2-(1-(2,6-di(pyrazol-1-yl)-4-methylpyridyl)-4,5-(4,5-bis(propylthio)-tetrathiafulvalenyl)-1H-benzimidazol-2-yl)-pyridine ligand (L), 1 equivalent of Ln(hfac)3·2H2O/Dy(tta)3·2H2O (hfac- = 1,1,1,5,5,5-hexafluoroacetylacetonate, tta- = 2-thenoyltrifluoroacetonate) and M(hfac)2·2H2O leads to the formation of heteroleptic 3d-4f dinuclear complexes of formula...

Multi-modal nanoprobe-enabled biosensing platforms: a critical review

“…At the same time, we also note that some materials themselves have the advantage of multi-modal signals, such as opto-magnetic materials 76 and some molecules based on lanthanides, 77 which can show both optical and magnetic properties. But they also have some inevitable defects: they may be easily affected by the external environment, which affects the stability of the material, and the signal tunability is limited in specific applications, 78,79 etc. Multi-modal nanoprobes have strong flexibility, and it is easier to obtain a significant performance improvement.…”
