The hybrid molecules composed of fulleropyrrolidine and poly(urethane amide) dendron of the third generation have been synthesized, and their self-assembling in THF/water mixtures has been studied. By TEM, AFM, and SAXS methods it was established that molecules form ribbonlike aggregates with the ordered layers of fullerene derivatives situated inside of the ribbons. Microscale length and high ratio width/thickness were detected for the ribbons. The ability of amides and urethanes to initiate a coupling of dendron fragments by means of hydrogen bonding has been considered as mainly responsible for anisotropic interaction of hybrid molecules and for the ribbonlike aggregates formation in THF/water mixtures.
