Thermally activated delayed fluorescence in a deep red dinuclear iridium( iii ) complex: a hidden mechanism for short luminescence lifetimes † (2023)
Journal Article
Pander, P., Zaytsev, A. V., Sil, A., Baryshnikov, G. V., Siddique, F., Williams, J. A. G., …Kozhevnikov, V. N. (2023). Thermally activated delayed fluorescence in a deep red dinuclear iridium( iii ) complex: a hidden mechanism for short luminescence lifetimes †. Chemical Science, 14, 13934-13943. https://doi.org/10.1039/d3sc04450e

The high luminescence efficiency of cyclometallated iridium(iii) complexes, including those widely used in OLEDs, is typically attributed solely to the formally spin-forbidden phosphorescence process being facilitated by spin–orbit coupling with the...

In this work, we introduce a spiro-fluorene unit into a phenylpyridine (CN)-type ligand as a simple way to deplanarize the structure and increase the solubility of the final platinum(II)···complex. Using a spiro-fluorene unit, orthogonal to the main... Read More about Unusual Excimer/Dimer Behavior of a Highly Soluble C,N Platinum(II) Complex with a Spiro-Fluorene Motif..

Rigidly linked dinuclear platinum( ii ) complexes showing intense, excimer-like, near-infrared luminescence (2023)
Journal Article

Rigidly linked dinuclear platinum( ii ) complexes showing intense, excimer-like, near-infrared luminescence. Journal of Materials Chemistry C Materials for optical and electronic devices, 11(43), 15335-15346. https://doi.org/10.1039/d3tc03432a

Many luminescent platinum(ii) complexes undergo face-to-face interactions between neighbouring molecules, leading to bimolecular excited states that may emit at lower energy (dimers and/or excimers). Detailed photophysical studies are reported on din... Read More about Rigidly linked dinuclear platinum( ii ) complexes showing intense, excimer-like, near-infrared luminescence.

Electroluminescence of Tetradentate Pt(II) Complexes: O^N^N^O versus C^N^N^O Coordination (2023)
Journal Article
Pander, P., *Gomes Franca, L., Dias, F. B., & Kozhevnikov, V. N. (2023). Electroluminescence of Tetradentate Pt(II) Complexes: O^N^N^O versus C^N^N^O Coordination. Inorganic Chemistry, 62(14), https://doi.org/10.1021/acs.inorgchem.3c00364

Alkylation of one of the phenolic hydroxyl groups in a salen-type tetradentate ligand changes the coordination mode from O^N^N^O to the cyclometallating C^N^N^O type. The ligand was used to synthesize a new cyclometalated luminescent Pt(II) complex 2... Read More about Electroluminescence of Tetradentate Pt(II) Complexes: O^N^N^O versus C^N^N^O Coordination.
