The synthesis, spectroscopic characterization, electrochemistry and photophysical measurements of new phenylenevinylene fullerodendrimers are described. Cyclic and Osteryoung square wave voltammetry studies indicate that prepared fullerodendrimers show improved electron affinity over the parent C-60. Photophysical investigations reveal a strong interaction between the dendrimers and C-60. (C) 2001 Elsevier Science Ltd. All rights reserved.

New dipolar and non-dipolar poly(phenylenevinylene) dendrimers bearing electron-donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta-substitution pattern, large Stokes shifts can be observed when
