synthesis of linear, unnatural amines and carboxylic acids, based on amide connectivity and possessing identical repeat unit architecture to that of analogous dendrimers, was undertaken to assess and compare their physical characteristics. For the series, unexpected insoluble behavior was observed at low molecular weights in contrast to their branched counterparts or other known linear dendritic analogs
基于酰胺连接性并具有与类似树枝状大分子相同的重复单元结构,线性、非天然胺和羧酸的合成被用来评估和比较它们的物理特性。对于该系列,与其支化对应物或其他已知的线性树枝状类似物相比,在低分子量下观察到出乎意料的不溶性行为。分子模型表明该系列具有高度的分子内和分子间氢键。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
