pH‐Responsive Luminescent Lanthanide‐Functionalized Gold Nanoparticles with “On–Off” Ytterbium Switchable Near‐Infrared Emission

Syntheses, Crystal structures, Magnetisms and Luminescences of two Series of Lanthanide Coordination Polymers Based on Tricarboxylic Ligand

“…Strikingly, well‐split peaks instead of single sharp transition are observed, with another weak band appears at 980 nm. A similar splitting has been reported previously, attributed to the crystal field or stark splitting . The characteristic NIR emissions in CP 12 demonstrate that the ligand transfers the absorbed energy effectively to the emitting level of Yb(III) centers.…”

Surface‐Modified Gold Nanoparticles Possessing Two‐Channel Responsive EuIII/TbIII Cyclen Complexes as Luminescent Logic Gate Mimics

“…This water molecule was displaced by the nta or DMAB antennae, resulting in modulation of the emission and change in from 1 to q Eu,Tb ≈0. For such complexes, a q‐value of 2 would be expected, but our previous work in the area has demonstrated that the thiol moiety can also bind to the metal ion centre, resulting in a lover q‐value . This was confirmed by synthesising an analogue of 1 , which lacked the thiol functionality, resulting in a q‐value of 2.…”

“…AuNPs were synthesised through using a modified Brust–Schiffrin method and coated with [Eu.1] 3+ , [Tb.1] 3+ or a 1:1 ratio by treating the synthesized AuNPs with appropriate solutions of [Eu.1] 3+ or [Tb.1] 3+ in 99 % H 2 O:DMSO . The resulting functionalised AuNPs were characterised by transmission electron microscopy (TEM) and dynamic light scattering (DLS), demonstrating the formation of spherical AuNPs (PDI 0.42, by DLS) with an average hydrodynamic diameter of ca.…”

Synthesis, crystal structure, and porosity of 1D coordination polymer of neodymium(III) with isonicotinic acid and dimeric complex of neodymium(III) with nicotinic acid

“…Large number of lan thanide metal organic frameworks (MOFs) with vari ous structures and interesting properties have been obtained by the self assembly of metal ions and organic ligands [10][11][12][13]. The design and control over lanthanides based frameworks are strongly influenced by various factors such as organic ligands [14], system atic pH value [15,16], template effect [17], and reac tion temperature [18]. The synthesis and functionality of MOFs and self assembled supramolecular coordi nation complexes have been recently reviewed [19,20].…”
