✦ Synopsis

Routes to the preparation of monomeric and colloidal C6o in micellar solutions of non-ionic surfactants are described. UV-visible spectra and small-angle neutron scattering provide clear evidence for these two different fom. The micelles serve to stabilise the excited triplet state 3C6o and the lifetime ~' T is increased by a factor of 3 as compared to 3C6o in toluene. Furthermore, with monomeric dispersions in the presence of the electron donor DABCO, the radical anion C~ is formed, with an unusually long lifetime ~'^ ffi 16 ms. This lifetime is approximately 270 times longer than for T-cyclodextrin-stabilised systems.

In this paper SANS results on C solutions are presented. The data analysis allows to determine the value of the gyration 60 radius of C dissolved in CS , a solvent capable to guarantee a good contrast for the neutron probe. The study indicates that the 60 2 gyration radius R is independent of concen

In the pursuit of a porphyrin-fullerene linked hybrid with increased soiubUity and superior cation complexation abilities, hybrid 1 was synthesized. The amphiphilic hybrid 1 was found to be slightly soluble in DMSO, displayed a lower affinity for metal cations than expected, and had a surprisingly h

## Abstract CdS nanoparticles of 4.5 nm diameter were synthesized in poly(2‐vinylpyridine) micellar cores which were obtained by solvating a polystyrene‐__block__‐poly(2‐vinylpyridine) block copolymer in polystyrene‐selective toluene. Then, a C~60~‐toluene solution was dispersed into the CdS micell
