Résumé
[60]Fulleropyrrolidine-containing poly(benzyl ether) dendrimers <b>1−4</b> were synthesized via 1,3-dipolar cycloaddition of amino acid and aldehyde derivatives and [60]fullerene. Their dielectric and electrooptical (Kerr effect) solution properties were studied and compared with poly(propyleneimine) dendrimers, namely DAB-<i>dendr</i>-(alkyl chain)<sub>n</sub> and DAB-<i>dendr</i>-(CN)<sub>n</sub>, and with known symmetrical and non-symmetrical poly(benzyl ether) dendrimers carrying benzyl groups ([G<sub><i>x</i></sub>]-[C]-[G<sub><i>x</i></sub>]) or benzyl and cyanobenzyl groups (CN<sub><i>n</i></sub>-[G<sub><i>x</i></sub>]-[C]-[G<sub><i>x</i>+1</sub>]), respectively. It was shown that <b>1−4</b> display similar polar and electrooptical characteristics independent of their dendrimer generation. This is in contrast to the reference dendrimers for which a strong dependence of total dipole moment on dendrimer generation was observed.
