In 1989, it was predicted that a change in dendritic shape to a nearly spherical one should occur upon increasing the generation number (Naylor, A. M.; Goddard, W. A., III; Kiefer, G. E.; Tomalia, D. A. J. Am. Chem. Soc. 1989, 111, 2339). The absence of long-range order required for X-ray analysis allowed only indirect evidence to be provided for this concept. This publication reports the synthesis
1989 年,据预测,随着代数的增加,树枝状形状会变成接近球形的形状(Naylor, AM; Goddard, WA, III; Kiefer, GE; Tomalia, DAJ Am. Chem. Soc. 1989, 111, 2339)。X 射线分析所需的长程阶数的缺失只允许为这一概念提供间接证据。该出版物报告了基于 AB3 结构单元 3,4,5-三羟基苯甲酸甲酯的三代自组装单树突的合成。第一个 3,4,5-tris[p-(n-dodecan-1-yloxy)benzyloxy] 苯甲酸和第二代甲基 3,4,5-tris3',4',5'-tris[ p-(n-dodecan-1-yloxy)benzyloxy]benzyloxy}苯甲酸酯单树突自组装成圆柱形超分子树枝状大分子,在二维 p6mm 晶格中自组织。第三代木薯 3,4,
