Photoswitchable monolayers on silicon

Published on November 13, 2013

Silicon is one of the most relevant materials for nanotechnology and semiconductor devices. We are presenting the design of naphthopyrans and fulgimides for surface applications and ATR-FTIR studies on silicon(111). The video includes the formation of photoswitchable alkyl monolayers with fulgimide headgroups on silicon(111).

Karola Rück-Braun studied Chemistry at the University of Mainz where she received her Diploma in 1988 and her PhD in 1992. After postdoctoral studies at the University of Cambridge (UK) in 1992-1993, she obtained her Habilitation at the University of Mainz in 1998, and became a Professor of Organic Chemistry at the Technische Universität Berlin in 2000. Her research interests are directed towards the synthesis of heterocycles and photoswitches, and include the design of photoswitches for biological and nanotechnological applications.

Diana Liebmann studied Chemistry at the Technical University of Berlin and is currently working on her PhD regarding the synthesis of tailor made photoswitches for biological and surface applications.

Andreas Hebert studied Chemistry at the University of Leipzig and is currently working on his PhD at the Technical University of Berlin regarding photoswitches and their immobilization and characterization on silicon surfaces.

Christoph Barta studied Chemistry at the Technical University of Berlin and just started his PhD. regarding the synthesis of photoswitches and their immobilization on semiconductor surfaces.
