Polar and electrooptical properties of [60]fullerene-containing poly(benzyl ether) dendrimers in solution

[60]Fulleropyrrolidine-containing poly(benzyl ether) dendrimer 1-4 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-dendr-(alkyl chain)(n) and DAB-dendr-(CN)(n), and with known symmetrical and non-symmetrical poly(benzyl ether) dendrimers carrying benzyl groups ([G(x)]-[C]-[G(x)]) or benzyl and cyanobenzyl groups (CNn-[G(x)]-[C]-[G(x+1)]), respectively. It was shown that 1-4 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.
