My research workMy work's focus was on oxygen
sensors based on the luminescence quenching
of ruthenium(II) complexes, e.g. Ru(n-alkyl-ddp)3
ClO4 with n = 3, 6 or 8. Subjects were photochemical
behavior of the dyes (What role does oxygen
play? Which products are being formed? What
are relevant issues for their use in membranes?)
and their electrochemical behavior. Other interests
include spectroelectrochemistry and impedance
measurements, sterilizable membranes and alternative
measurement techniques. See also the project
description sheet Luminescence-based
oxygen sensing with ruthenium(II) complexes
(pdf, 84k, 1 page, English). My thesis "Ruthenium(II) diimine complexes for luminescence-based oxygen sensors and Impedance spectroscopy of nitrogen dioxide-sensitive polymeric membranes" ( 284 pages, English, 5.9 MB) can be downloaded as a pdf-file. An abstract is available in English and German, a separate page lists all the references cited in my thesis. Despite all this sensor stuff, I did my diploma thesis on a different matter, namely Scanning Near-field Microscopy (SNOM). See my diploma thesis (121 pages, German, 4.8 MB) "Fluorescence studies and polymer modification on a nanometer scale with a Scanning Near-Field Optical Microscopy".

CurriculumI have studied chemistry (emphasis on analytical/physical chemistry)at ETH Zürich from 1991 to 1996, with the last year actually studying at the Université Paul Sabatier in Toulouse with the late ERASMUS program. After a diploma thesis on Scanning Near-Field Optical Microscopy (SNOM) at the group of Professor Renato Zenobi at ETH Zürich I started my thesis at the group of Prof. Ursula Spichiger-Keller at the Centre for Chemical Sensors, bioAnalytical Chemistry and Biosensors (CCS) at Technopark Zürich. I spent six weeks of PhD research at the Changchun Institute of Applied Chemistry in Changchun, China where I did cyclic voltammetry and spectroelectrochemical experiments. Financial support from the late "Stipendienfonds der Basler Chemischen Industrie zur Unterstützung von Doktoranden auf dem Gebiete der Chemie, der Biotechnologie und der Pharamazie" and now from the Roche Research Foundation as well as the Swiss Asia Foundation scholarship for my research stay at the Changchun Institute of Applied Chemistry in Changchun, China (November/December 1998) is gratefully acknowledged.
