Excitation dynamics of pyrenyl labeled polyallylcarbosilane dendrimers

Pyrenyl labeled anesiloxane dendrimers and carbosilane hyperbranched polymers have been investigated with the use of various types of fluorescence experiments. Both steady-state and time-resolved fluorescence quenching of a probe molecule, pyrenyl excimer formation as well as polarization measurements were employed. It was shown that different aspects of dendritic polymers structure and their dynamics may be evaluated and visualized.
