9622609 Newkome这项研究的首要主题是研究经过内部修饰的树枝状大分子(级联大分子)的制备、结构方面和化学性质。根据这一目标，设计和合成面向应用的树枝状构建块，具有掩蔽的或惰性的可变形功能，可在树枝状大分子构建后获得使用。项目目标包括：1)构建功能不同的树枝状构造块，用于将面向应用的功能特定地结合到树枝状大分子中。2)构建具有能够与其他树枝状大分子形成连接的分隔部分的树枝状大分子。3)多个树枝状组件(树枝状文库)的整合(“组合”)构建。4)单分子胶束约束模板化制备单分散、小颗粒、半导体微晶(又称量子点)。5)将半导体微晶精确排列成三维超阵列，实现Q粒子电子耦合“微调”。这项研究的优点依赖于与高度支化的、特殊设计的大分子的物理化学性质相关的化学研究，以及这些性质所固有的随之而来的效用。这项研究的结果将为理解发生在“设计者”反应环境中的化学现象奠定基础。***

9622609 Newkome The overriding theme of this research concerns the investigation of the preparation, structural aspects, and chemical properties of dendrimers (cascade macromolecules) that have been internally modified. Pursuant to this goal is the design and synthesis of application-oriented dendritic building blocks possessing masked, or inert, transformable functionality to be accessed for use after dendrimer construction. Project goals include: 1) Construction of functionally differentiated dendritic building blocks for the site-specific incorporation of application-oriented functionality into dendrimers. 2) Construction of dendrimers with compartmentalized moieties capable of forming connections with other dendrimers. 3) Concommitant (`combinatorial") construction of multiple, dendritic assemblies (dendritic libraries). 4) Unimolecular micellar constrained and templated preparation of monodisperse, small particle, semiconductor crystallites (also described as "quantum dots"). 5) Precise arrangement of semiconductor crystallites into three-dimensional superarrays allowing Q-particle electronic coupling "fine tuning". %%% The merits of this research rely on the study of the chemistry associated with physicochemical properties of highly branched, specifically designed, macromolecules, and the attendant utility inherent in those properties. Results of this research will expand foundations for understanding of chemical phenomena occurring within "designer" reaction environments. ***
