Temperature dependence of the conversion efficiency of photochromic perylene bisimide dithienylcyclopentene triads embedded in a polymer.

Physical chemistry chemical physics : PCCP

Thurn J, Maier J, Pärs M, Gräf K, Thelakkat M, Köhler J.
PMID: 28926050
Phys Chem Chem Phys. 2017 Oct 04;19(38):26065-26071. doi: 10.1039/c7cp03634e.

Photochromic molecules that are covalently linked to a strong fluorophore combine the requirements of external control and strong fluorescence, which will become increasingly important for super-resolution microscopy techniques based on single molecules. However, given the bulky structure of such...

Spin orientations of the spin-half Ir(4+) ions in Sr3NiIrO6, Sr2IrO4, and Na2IrO3: Density functional, perturbation theory, and Madelung potential analyses.

The Journal of chemical physics

Gordon EE, Xiang H, Köhler J, Whangbo MH.
PMID: 27004892
J Chem Phys. 2016 Mar 21;144(11):114706. doi: 10.1063/1.4943889.

The spins of the low-spin Ir(4+) (S = 1/2, d(5)) ions at the octahedral sites of the oxides Sr3NiIrO6, Sr2IrO4, and Na2IrO3 exhibit preferred orientations with respect to their IrO6 octahedra. We evaluated the magnetic anisotropies of these S...

[News in endocrinology: Management of asymptomatic primary hyperparathyroidism in 2014].

PMID: 25799652
Rev Med Suisse. 2015 Jan 14;11(456):58-61.

Primary hyperparathyroidism, a disorder in wich there is a hypercalcemia caused by autonomous hypersecretion of parathormone, usually by parathyroid adenoma. It is asymptomatic in most cases. After excluding a cause of secondary elevation of parathyroid hormone, a search for...

Deliberate Switching of Single Photochromic Triads.

Scientific reports

Maier J, Pärs M, Weller T, Thelakkat M, Köhler J.
PMID: 28139764
Sci Rep. 2017 Jan 31;7:41739. doi: 10.1038/srep41739.

Photochromic molecules can be reversibly converted between two bistable conformations by light, and are considered as promising building blocks in novel macromolecular structures for sensing and imaging techniques. We have studied individual molecular triads consisting of two strong fluorophores...

Single-crystal X-ray structure analysis of the superionic conductor Li10GeP2S12.

Physical chemistry chemical physics : PCCP

Kuhn A, Köhler J, Lotsch BV.

Phys Chem Chem Phys. 2013 Jul 28;15(28):11620-2. doi: 10.1039/c3cp51985f. Epub 2013 Jun 14.

Tetragonal Li10GeP2S12 (LGPS) is the best solid Li ion conductor known to date. So far, the structure of the electrolyte was only determined from powder diffraction and Rietveld refinement. Here, we present the first single-crystal structure analysis of the...

Efficient transport of excitation energy over long distances is a key process in light-harvesting systems, as well as in molecular electronics. However, in synthetic disordered organic materials, the exciton diffusion length is typically only around 10 nanometres (refs 4,...
