摘要：

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. (C) 1998 Elsevier Science B.V. All rights reserved.
