Structural determination of a photochemically active diplatinum molecule by time-resolved EXAFS spectroscopy.
TLDR
The strengthening of the Pt-Pt interaction is accompanied by a weakening of the ligand coordination bonds, resulting in an elongation of the platinum-ligand bond that is determined for the first time by time-resolved X-ray absorption spectroscopy.

An alternative route to highly luminescent platinum(II) complexes: cyclometalation with N=C=N-coordinating dipyridylbenzene ligands.
TLDR
The remarkable luminescence properties of the platinum(II) complex of 1,3-di(2-pyridyl)benzene, acting as a terdentate N=C=N-coordinating ligand cyclometalated at C2 of the benzene ring, have been investigated and the emission is attributed to an excited state of primarily (3)pi-pi character.

Dinuclear Ruthenium(II) Complexes as Two-Photon, Time-Resolved Emission Microscopy Probes for Cellular DNA**
TLDR
Ruthenium(II) luminophores are used as phosphorescent lifetime imaging microscopy (PLIM) probes for nuclear DNA in both live and fixed cells, leading to previously unattainable levels of sensitivity, and autofluorescence-free imaging.

Luminescent cyanometallates based on phenylpyridine-Ir(III) units: solvatochromism, metallochromism, and energy-transfer in Ir/Ln and Ir/Re complexes.
TLDR
These effects are however modest because of (i) the presence of only two cyanide groups, and (ii) the fact that the lowest-energy excited state has a substantial (3)LC component and is therefore not purely charge-transfer in nature.

Anthracene as a sensitiser for near-infrared luminescence in complexes of Nd(III), Er(III) and Yb(III): an unexpected sensitisation mechanism based on electron transfer.
TLDR
The ligand L(1), which contains a chelating 2-(2-pyridyl)benzimidazole (PB) unit with a pendant anthacenyl group An connected via a methylene spacer, was used to prepare the 8-coordinate lanthanide(III) complexes which have been structurally characterised and all have a square antiprismatic N(2)O(6) coordination geometry.
