Winziger magnetischer Schalter entdeckt

Wissenschaftler der Uni Kiel entwickeln molekulare Maschine in Plattenspielerform

(PresseBox) (Kiel, )
Einer Kieler Forschergruppe um den Chemiker Professor Rainer Herges ist es erstmals gelungen, den magnetischen Zustand eines einzelnen Moleküls bei Raumtemperatur gezielt zu steuern. Die Arbeit erscheint am heutigen Freitag (28.01.2011) in der Zeitschrift Science. Das schaltbare Molekül, Ergebnis eines Teilprojekts des Sonderforschungsbereichs 677 "Funktion durch Schalten", könnte beim Bau winziger elektromagnetischer Speicher ebenso zum Einsatz kommen wie in der Medizin.

Die Wissenschaftler der Christian-Albrechts-Universität zu Kiel entwickelten eine molekulare Maschine, die ähnlich wie ein Plattenspieler aufgebaut ist. Das Molekül besteht aus einem Nickelion, das von einem Ring aus Farbstoff (Porphyrin) umgeben ist, und einem Stickstoffatom, das wie an einem Qgdfpj lbguaqw ujvzpae.
