S. Aroua, Y. Yamakoshi
The 1,3-dipolar cycloaddition of an azomethine ylide (Prato reaction) with M(3)N@I(h)-C(80) (denoted as M(3)N@C(80); M = Sc, Lu, Y, Gd) was carried out to obtain fulleropyrrolidinebis(carboxylic… Expand
Endohedral metal-induced regioselective formation of bis-Prato adduct of Y3N@I(h)-C80 and Gd3N@I(h)-C80.
S. Aroua, M. Garcia-Borràs, Marc F. Bölter, S. Osuna, Y. Yamakoshi
Regioselective bisaddition of M3N@Ih-C80 (M = Y, Gd) was observed for the first time in the Prato reaction with N-ethylglycine and formaldehyde. The main kinetic bisadduct of Y3N@C80 was determined… Expand
Water-soluble C60- and C70-PVP polymers for biomaterials with efficient (1)O2 generation.

Y. Yamakoshi, S. Aroua, Thach-Mien D. Nguyen, Y. Iwamoto, T. Ohnishi
Faraday discussions
The photoinduced reactive oxygen species (ROS) generation from several water-soluble fullerenes was examined. Macromolecular or small molecular water-soluble fullerene complexes/derivatives were… Expand
RAFT synthesis of poly(vinylpyrrolidone) amine and preparation of a water-soluble C60-PVP conjugate
S. Aroua, E. G. V. Tiu, M. Ayer, T. Ishikawa, Y. Yamakoshi
An amine-terminated poly(vinylpyrrolidone) (PVP) was prepared by radical polymerization using a xanthate-type RAFT agent. The obtained PVP (ca. 20 kDa) was converted to PVP-NH2, which was coupled… Expand
