Rational reductive fusion of two heterometallic clusters: formation of a highly stable, intensely phosphorescent Au–Ag aggregate and application in two-photon imaging in human mesenchymal stem cells
Igor O. Koshevoy,Yi-Chih Lin,Yu-Chun Chen,Antti J. Karttunen,Matti Haukka,Pi-Tai Chou,Sergey P. Tunik,Tapani A. Pakkanen +7 more
TL;DR: An unprecedented Au-Ag alkynyl-diphosphine aggregate obtained via CO-reduction of a mixture of simple reagents, exhibits intense room-temperature phosphorescence free from O(2) quenching, and serves as an excellent phosphorescence dye suited for both one- and two-photon imaging in human stem cells.

Icosahedral and ring-shaped allotropes of phosphorus.
TL;DR: The high thermodynamic stability of the phosphorus nanostructures suggests their experimental synthesis to be viable, and both the cages and the rings are thermodynamically favored over the white phosphorus.

Luminescent Triphosphine Cyanide d10 Metal Complexes
Gomathy Chakkaradhari,Yi-Ting Chen,Antti J. Karttunen,Minh Thuy Thuy Dau,Janne Jänis,Sergey P. Tunik,Pi-Tai Chou,Mei-Lin Ho,Igor O. Koshevoy +8 more
TL;DR: The NMR spectroscopic studies revealed that all of the complexes except 6 retain their structures in solution, and the title compounds are luminescent in the solid state, with quantum yields ranging from 8 to 87%.
