Carbosilanesiloxane dendrimers fluorescently labelled by pyrenyl on th
e central silicon atom Si-14(18)(Me) and Si-29(36)(Me) have been prepa
red, The evidence of excimer formation of pyrenyl dendrimer is obtaine
d using the time-correlated single-photon counting technique and stead
ystate fluorescence spectroscopy, The similarity of the process of the
pyrenyl excimer formation for both different generations of dendrimer
has been demonstrated. (C) 1997 Elsevier Science S.A.
