A facile methodology to prepare N-heterocyclic carbene (NHC)-terminated polymers as surface ligands to functionalize gold nanoparticles (AuNPs) is reported.

We report the synthesis and characterization of C 2 -symmetrical lanthanide complexes supported by enantiopure hexadentate ligands derived from 1,2-diaminocyclohexane. Coordination of (R,R)-or (S,S)-N,N,N′,N′-tetrakis(2-pyridylmethyl)-trans-1,2-diaminocyclohexane (tpdac) to samarium, europium, terbium, and dysprosium generates the corresponding C 2 -symmetrical (tpdac)Ln(OTf) 3 complexes in high yields. The tpdac ligands are competent sensitizers for lanthanide luminescence, yielding modest emissions (Φ of ≤28%). Additionally, the complexes exhibit strong circularly polarized luminescence (|g lum | values of up to 0.13, 0.09, 0.22, and 0.15 for Sm, Eu, Tb, and Dy, respectively) in solution. We also observed that some transitions typically associated with small dissymmetry factors exhibit unusually high |g lum | values and, therefore, should not be overlooked in future studies.

We report the synthesis, characterization, solid‐state structure and solution behavior of simple lanthanide trifluoromethanesulfonate complexes supported by a hexadentate tetrakis(2‐pyridylmethyl)ethylenediamine ligand. The complexes' solid‐state structures exhibit different trifluoromethanesulfonate coordination, correlating with the size difference of the lanthanide ions. The ligand is capable of sensitizing Nd, Sm, Eu, Tb, Dy, and Yb yielding metal‐centered emission with moderate quantum yields.
