Probing the Effects of Ligand Isomerism in Chiral Luminescent Lanthanide Supramolecular Self‐Assemblies: A Europium “Trinity Sliotar” Study

Abstract: "Trinity Sliotar" family: Chiral ligands containing pyridyl and naphthalene moieties were synthesized and characterized. These ligands were successfully used for the synthesis of Eu(III) bundles where chirality of the ligand is successfully transferred onto the lanthanide centre resulting in circularly polarized red luminescence.

This arrangement is consistent with the 1 H NMR chemical shifts for the pyridine and naphthalene groups in the trefoil knot complexes in solution (Figure 1c).…”

“…[16][17][18][19]53,58,[138][139][140][141] Hence they lend themselves to use in other applications such as in biological sensing, OLEDs, and as imaging agents, etc. 142,143 Flood and co-workers proved that btp-ligand 3a could form a stable coordination complex with Eu(III), which is to the best of our knowledge, the first example of such a system in the literature.…”

“…[7][8][9] Various types of luminescent lanthanide complexes have been reported to date. [10][11][12][13][14][15][16][17][18][19][20][21] Lanthanide complexes with asymmetric coordination structures exhibit high emission quantum yields (Φff) and large radiative rate constants (kr). [22,23] Lanthanide complexes generally provide eightcoordinate square anti-prism structures that are categorized as D4d in point group theory (8-SAP, Figure 1a).…”
