EXCITATION DYNAMICS OF PYRENYL LABELED POLYALLYLCARBOSILANE DENDRIMERS

Pyrenyl labeled anesiloxane dendrimers and carbosilane hyperbranched p olymers have been investigated with the use of various types of fluore scence experiments. Both steady-state and time-resolved fluorescence q uenching of a probe molecule, pyrenyl excimer formation as well as pol arization measurements were employed. It was shown that different aspe cts of dendritic polymers structure and their dynamics may be evaluate d and visualized. (C) 1998 Elsevier Science B.V. All rights reserved.
