Acknowledgements

I would like to express my sincere gratitude to Prof. Dr. B. König, for his continued
guidance, advice and encouragement throughout this work.

Thanks are extended to the analytical departments of the University of Regensburg for
the prompt and accurate measurement of my numerous, often difficult samples. Special
thanks to Dr. T. Burgemeister, Mr. F. Kastner, Ms. N. Pustet, Ms. A. Schramm and Ms.
G. Stühler (NMR), Dr. K. K. Mayer, Mr. J. Kiermaier and Mr. W. Söllner (MS), Mr. G.
Wandinger, Ms. S. Stempfhuber and Mr. H. Schüller (elemental analysis), Dr. M. Zabel
(X-ray crystallography) and Dr. R. Vasold (HPLC).

My special thanks go to:
All colleagues, past and present at the University of Regensburg, for making the
working environment positive, constructive, as well as relaxed.

Daniel Vomasta, Andreas Grauer and Nicole Holub for their efforts during their
research period in my laboratory.

Daniel Frank for his work during his Zulassungsarbeit.

Mrs. Helga Leffler-Schuster for the potentiometric titrations and here marvellous
reports about foreign countries.

Dr. Thomas Walenzyk, Daniel Vomasta, Eva Engel, Michael Egger and Stefan Ritter
for their corrections of this work.

Dr. Maria Teresa Hechavarria Fonseca and Thomas Suhs for the fabulous time in
laboratory.

My very special thanks go to:
Stefan Ritter for the wonderful time in China, the very delicious dinners and his
infectious laughter.
Eva Engel for all the tasty cakes and sweets. Thanks also for the time at Tai-Bo lessons
and all the climbing trips to Schönhofen.

Stefan Miltschitzky for his fabulous cooking and the perfect time in Italy. Thank you for
your tireless microcalorimetrical titrations.

Giovanni Imperato for making live better since he appeared in our working group.
Thanks Gio for all your Italian dishes and showing me how to climb up mountains.
Thank you also for one unforgettable weak in my life staying in Italy.

Dr. Christian Mandl and Dr. Christoph Bonauer for cooperation in two great projects
and all the great ideas. Thank you also for all the private discussions until the early
mornings. I am not able to say how much they influenced my life.

Dr. Thomas Walenzyk for showing up in my live. Thanks Thomas for all the evenings,
discussions, and support in any situations of my life.

Christian Geiger for three wonderful years in our apartment.

Doris Huber for showing me that there is still a lot more in life than chemistry and
working. Thanks for your patience and your love.

My parents for all their support and love. Content
