Abstract [en]

The frontier electronic structures of a series of organic dye molecules containing a triphenylaminemoiety, a thiophene moiety and a cyanoacrylic acid moiety have been investigated byphotoelectron spectroscopy (PES), X-ray absorption spectroscopy (XAS), X-ray emissionspectroscopy (XES) and resonant photoelectron spectroscopy (RPES). The experimental resultswere compared to electronic structure calculations on the molecules, which are used to confirmand enrich the assignment of the spectra. The approach allows us to experimentally measure andinterpret the basic valence energy level structure in the dye, including the highest occupied energylevel and how it depends on the interaction between the different units. Based on N 1s X-rayabsorption and emission spectra we also obtain insight into the structure of the excited states,the molecular orbital composition and dynamics. Together the results provide an experimentallydetermined energy level map useful in the design of these types of materials. Included are alsoresults indicating femtosecond charge redistribution at the dye/TiO2 interface.
