Introduction:

From september 2004 to oktober 2008 I did a PhD in chemistry at the Vrije Universiteit in Amsterdam at the research-group Analytical Chemistry and Applied Spectroscopy. I defended my thesis on december the 7th. My supervisors were Prof. dr. Gooijer and dr. Ariese.

The focus of my thesis is on molecules that contain both a proton donating and a proton accepting site. These compounds undergo complicated photochemical and photophysical processes, including excited-state intramolecular proton transfer (ESIPT). They also tend to form dimers or other associates so that intermolecular or double proton transfer may play a role as well.
