and second-generation polyphenylene dendrimers were synthesized starting from benzophenone as core. Variation of the size and the density of the dendrimer shell resulted in different isolation of the cores. To investigate the effect of shielding upon the reactivity of the core, chemical functionalizations as well as the alkali-metal reduction of the encapsulated benzophenone core were performed. The
以二苯甲酮为核心合成了第一代和第二代聚苯撑树枝状聚合物。树枝状聚合物壳的尺寸和密度的变化导致核的不同分离。为了研究屏蔽对核反应性的影响,进行了化学官能化以及封装的二苯甲酮核的碱金属还原。本文提出的合成概念为空间定义明确的球形纳米粒子开辟了道路,该纳米粒子在中心具有单一的孤立功能。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
