Summary:
Ever since Hennig Brand's discovery in 1669, elementary phosphorus has fascinated chemists around the world. It is industrially produced by the ton and its compounds have numerous applications in materials science and the life sciences. The main known forms of the element are white, red, and black phosphorus. Chemists have now succeeded in creating a positively charged pure phosphorus compound.

Ever since Hennig Brand's discovery in 1669, elementary phosphorus has fascinated chemists around the world. It is industrially produced by the ton and its compounds have numerous applications in materials science and the life sciences. The main known forms of the element are white, red, and black phosphorus.

In addition, there are hundreds of compounds in which phosphorus is present as an anion, a negatively charged ion. Some of these compounds have very useful properties. They are suitable for use as electrode materials for lithium-ion batteries, for instance. But all attempts in the past decades to synthesize a positively charged cation as a complement to the known negative ion have failed. A research team led by Prof. Dr. Ingo Krossing from the Faculty of Chemistry, Pharmacy, and Earth Sciences of the University of Freiburg has now succeeded in creating a positively charged pure phosphorus compound.

The results have been published in a recent issue of the journal Angewandte Chemie.

The team used the stabilizing effect of an non-reactive counterion to synthesize sizable quantities of the first ever pure phosphorus cation [P9]+ both in solution and in solid form. In addition, the salt obtained in this way remains stable for weeks at room temperature. It is thus finally possible to perform chemical reactions with this particle, which was previously known only from gas-phase experiments. Due to its broad availability, it can be used in fundamental as well as applied research. One promising possibility is the semiconductor synthesis of the compound gallium phosphide, which is relevant for blue light-emitting diodes (LED).

Porsche CEO Says Supercar Is Not Dead: Cue the Spyder 918

TheStreet (Apr. 16, 2014) — The Porsche Spyder 918 proves that, in an automotive world obsessed with fuel efficiency, the supercar is not dead. Porsche North America CEO Detlev von Platen attributes the brand's consistent sales growth -- 21% in 2013 -- with an investment in new technology and expanded performance dynamics. The hybrid Spyder 918 has 887 horsepower and 944 lb-ft of torque, but it can run 18 miles on just an electric charge. The $845,000 vehicle is not a consumer-targeted vehicle but a brand statement.
