Boron Dipyrromethene Chromophores: Next Generation Triplet Acceptors/Annihilators for Low Power Upconversion Schemes
Journal of the American Chemical Society, 130(48), 16164–16165.
Contributors: T. Singh-Rachford*, A. Haefele *, R. Ziessel* & *
TL;DR:
The current systems represent the first examples of photon upconversion where aromatic hydrocarbons do not serve the role of triplet acceptor/annihilator and the nature of the current chromophore compositions permitted highly reproducible upconverted quantum efficiency determinations while permitting the evaluation of the triplet-triplet annihilation quantum yields in both instances.

Ligand Localized Triplet Excited States in Platinum(II) Bipyridyl and Terpyridyl Peryleneacetylides
Inorganic Chemistry, 47(10), 4348–4355.
Contributors: A. Rachford *, S. Goeb *, R. Ziessel* & *
TL;DR:
The transient difference spectra of the two title compounds display excited-state absorptions largely attributable to perylene localized (3)IL states yet exhibit somewhat attenuated excited- state lifetimes relative to those of the phosphine model chromophores, which may suggest the involvement of the energetically proximate (3]CT triplet state exerting an influence on excited-State decay.

Contributors: M. Muro*, S. Diring *, X. Wang *, R. Ziessel* & *
TL;DR:
The chelation of Zn (II) to 1 is acid-base in nature, and its Lewis acidity renders the highest occupied molecular orbital level in 1 much less electron-rich, which induces a blue shift in both the absorption and emission spectra, indicating that these emitting states are inverted relative to room temperature.
