• Physicists develop an innovative light source
  

  Tiny components with the ability to emit single particles of light are important for various technological innovations. Physicists of the Universities of Würzburg, Stuttgart and Ulm have made significant progress in the fabrication of such structures. Why are researchers interested in light sources more

• Sensitive to Oxygen: Phosphorescent iridium(III) porphyrin complexes, new tunable oxygen indicators

  Monitoring the amount of oxygen in living tissues accurately is a valuable tool in biomedical science, because it enables the elucidation of the course of metabolic processes or the detection of diseases or anomalies. Metal complexes that absorb and emit light are useful as sens more

• Helpers of all sizes for analysts
  

  Geologists analyze soil samples, the oil industry studies crude oil, and the steel industry wants to know the composition of slag. These are completely different fields, but all begin the analysis process with a high-temperature fusion treatment of the samples. But what equipment should be used for the fusion process? Platinum crucibles are ideally suited for the job, and are used in industrial and scientific laboratories around the world. Heraeus is a leading global manufacturer of platinum crucibles. It is remarkable that after over 130 years, we are still finding ways to improve this product more

• Monitoring the on–off switching of the electronic communication in diethynylplatinum(II)-bridged dyads using triplet energy transfer

  Despite conjugation and downhill manifolds in [Ir]–[Pt]–[ZnTPP] ([ZnTPP] = (tetraphenylporphyrin)zinc(ii), [Ir] = bis(phenylpyridinato)(bipyridine)iridium(iii), [Pt] = trans-C [[triple bond, length as m-dash]] CPt(PBu3)2-C [[triple bond, length as m-dash]] C), essentially no T1[Ir] → S1/T1[ZnTTP] en more

• Acceptorless Dehydrogenation of Nitrogen Heterocycles with a Versatile Iridium Catalyst

  Gas up: A cyclometalated iridium complex is found to catalyze the dehydrogenation of various benzofused N‐heterocycles, thus releasing H2. Driven by as low as 0.1 mol % catalyst, the reaction affords quinolines, indoles, quinoxalines, isoquinolines, and β‐carbolines in high yields. more

• Theoretical Study on Cationic Iridium(III) Complexes with a Diphosphane Ligand – Geometry, Electronic Properties, and Application for Light‐Emitting Electrochemical Cells

  Abstract A DFT/time‐dependent DFT (TD‐DFT) investigation was conducted on a series of cationic iridium(III) complexes with 2‐phenylpyridine (ppyn) derivatives and a diphosphane (PPn) ancillary ligand to shed light on the effects of stereoisomerism and ligand substituents on the photophysical pro more
