合成了富勒烯吡咯烷与第三代聚氨基甲酸酯酰胺树枝状分子的杂化分子，并研究了它们在THF/水混合溶剂中的自组装行为。通过TEM，AFM和SAXS方法，它被建立，分子形成带状聚集体与位于带状物内部的富勒烯衍生物的有序层。微尺度的长度和高比率的宽度/厚度被检测到的条带。酰胺和双酰胺通过氢键引发树枝状片段偶联的能力被认为是混合分子的各向异性相互作用和在THF/水混合物中形成带状聚集体的主要原因。
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.
