Photoisomerisation and Ligand-Controlled Reversible Aggregation of Azobenzene-Functionalised Gold Nanoparticles

Anja Köhntopp, Alexandra Dabrowski, Michal Malicki and Friedrich Temps
Chem. Commun. 50 (2014).  DOI: 10.1039/C4CC02250E.
 

 

The photochemical behaviour of functionalised gold nanoparticles (AuNPs) carrying azobenzene- thiolate/alkylthiolate monolayers was investigated. Repeated trans-cis and cis-trans isomerisation cycles could be performed in all cases with high efficiency. Reversible photoinduced aggregation was observed when azothiolates with long alkyl spacers (≥ C7) were combined with short (C5) alkylthiolate coligands. The choice of coligand thus offers control over the aggregation properties of the nanoparticles.

Uta Corinna Stange wins BASF Prize for best Master Degree in 2012, Mark Dittner receives B.Sc. Prize

Two BASF Prizes for the best Master Degrees in 2012 were awarded at this years Christmas Colloquium of the Kiel Division of the German Chemical Society (GDCh), one of them went to Uta Corinna Stange. In her Thesis project, Uta studied the temperature dependence of the ultrafast electronic deactivation of 7H-adenine. She was the first to measure the existence of an activation energy for the electronic deactivation of 7H-Ade. Apparently, the excited wavepacket can be trapped in a shallow potential energy well en route to the conical intersection with the ground state. Vibrational excitation helps the wavepacket to escape from the well.

Kiel Cluster of Excellence Future Ocean gets funding for phase II

Champagne bottles were opened after the announcement by the German Research Foundation (DFG) on June 15 to fund the Excellence Cluster "Future Ocean" for a second five-year period. The DFG also announced continued funding for the Excellence Cluster "Inflammation at Interfaces" and the Graduate School "Human Development in Landscapes". The application for the Cluster "Materials for Life" did not win, but Nano and Surface Sciences with heavy involvement of the Chemistry and Physics Departments will remain the fourth research focus of CAU.
The Future Ocean
How do micro-scale processes at ocean interfaces affect fluxes of climate-relevant substances? This is the key question of the new Research Area R7: Ocean Interfaces of Future Ocean, where Physical Chemistry is of central importance. The research combines state-of-the-art molecular, microbiological and biogeochemical analytical techniques, laser spectroscopy, micro- and mesocosm experimentation, in-situ measurements and theoretical modeling. Three research foci have been identified:

Research Area R7


Focus 1
investigates formation, retention and emission processes of climate-relevant substances.

Focus 2 links biological imprints on extracellular organic matter to interface properties by investigating the accumulation of organic substances and their intense microbial transformation in the surface ocean boundary layer.

Focus 3 investigates (i) chemical aspects of the ocean as a major source and sink for radiatively and chemically active atmospheric trace gases and (ii) the specific roles of the prevalent organic microlayer in sea-air gas exchange processes and as a biochemical reactor.

Background Information on the Oil Accident in the Gulf of Mexico

The explosion of the Deepwater Horizon platform on 22 April 2010 caused the second-largest man-made oil pollution of the sea and the surrounding shores ever.  780 Million Liters of crude oil flowed into the Gulf waters, where they caused severe damage to the unique ecosystems along the Louisiana coastline, in the Mississippi delta, and on the shores of the adjacent states.

The estimation of the ecological and economic consequences of the accident is highly complex and poses many challenging questions.  Geologists, chemists, oceanographers, biologists, lawyers, and economists of the Kiel Cluster of Excellence "The Future Ocean" ("Der Ozean der Zukunft") share their insights into the problems involved with the stopping of the leak, the consequences of the pollution, and the future research needs in a 40 page background paper.

The 2008 Familie Schindler Förderpreis for their outstanding Ph.D. theses in Physical Chemistry has been presented to Dr. Angela Gaber and to Dr. Harald Studzinski.  Harald obtained his Ph.D. in the group of Prof. Temps in 2007 with a thesis on "Ultrafast Radiationless Dynamics of Selected Electronically Excited Aromatic Molecules by Femtosecond Time-Resolved Mass Spectrometry and Photoelectron Imaging". He studied the distinctive electronic relaxation dynamics in hexa- and pentafluorobenzene and in pyrrole and a series of methyl-substituted pyrroles using a combination of novel time-resolved techniques. His work has implications for understanding the photochemistry and photophysics of DNA, the "molecule of life", and is of fundamental importance for developing organic molecule based solar cells helping to sustain our future energy needs.  Angela received her Ph.D. in 2007 in the group of Prof. Grotemeyer.  Both have since accepted top level R&D positions at leading industrial companies.

November 23: "The 2007 Night of the Profs"

Discover science - at a big CAU science party - in five lecture theatres non-stop from 8 pm to 2 am.

The 2007 Night of the Profs was a big success.  The lecture halls were packed until 2 am.  An audience of about two hundred, among them many high school students, university students from chemistry and different other fields, young and old scientists, and interested citizens, gathered to listen to Prof. Temps' talk on "How our DNA protects itself from UV Radiation Damage - New Insights on Hydrogen Bonds" in lecture theatre A from 1 - 2 am.  Many listeners, who did not arrive early, stood in the back of the lecture hall to learn about research results on the photophysics and photochemistry of the arguably most important molecules of life, the DNA and its building blocks.

Dr. Jens Riedel receives 2007 Familie Schindler Förderpreis for an outstanding Ph.D. thesis in Physical Chemistry

Jens obtained his Ph.D. in 2006 with a thesis on "Investigations of Photo-Induced Molecular Dissociation Processes by Photofragment Imaging Spectroscopy", in which he applied photofragment imaging to a variety of exciting reactions, including the photo-induced N-H/N-D predissociaton processes of pyrrole and pyrrole-d1. He also developed a new Doppler-free variant for H-atom imaging.  He has since moved as post-doc with Prof. Kopin Liu to the Institute of Atomic and Molecular Sciences of the Academia Sinica in Taipeh, Taiwan, which under the leadership of 1986 Nobel Laureate Prof. Yuan T. Lee has grown into a world-renowned institute.

Tiny Switches with Huge Effects. New SFB 677 in Kiel takes off!

SFB 677 "Function by Switching"

In the new Collaborative Research Centre (Sonderforschungsbereich) SFB 677 "Function by Switching" at Kiel, work groups from the Chemistry, Material Science, and Physics Departments at CAU Kiel develop tiny molecular switches driven by light to realize new functions and functional materials. The SFB, inaugurated July 1 2007, is chaired by Prof. Rainer Herges of the Otto Diels Institute of Organic Chemistry.  We participate with a collaborative project led by Prof. Bernd Hartke, Dr. Falk Renth, and Prof. Temps, in which we explore the dynamics of photochromic molecular switches in solution and more complex molecular environments using femtosecond spectroscopy and by quantum chemical calculations (SFB project A1). 

See more information on SFB 677 and more on subproject A1 (Hartke, Renth, Temps).

How life defends itself against UV light

Which strategies does nature exploit to protect the genomic information encoded in the DNA from photodamage by UV radiation - a major cause of mutations? Using sophisticated methods based on ultrafast spectroscopy, we have uncovered clever new defense mechanisms developed by evolution to protect the nucleic acid bases, which form the letters of our genetic code, from photochemical destruction.
