提出了一种基于可调的超分子模板机制形成有机-无机杂化纳米结构的新概念，该机制涉及多种类型的非共价相互作用。不同的有机-无机杂化结构具有狭窄的尺寸分布，由一个阳离子树状大分子、一个带相反电荷的二价重氮染料和CdS组成：首先，基于离子和π -π相互作用，构建了由几个100到1000个树状大分子组成的更大的超分子结构。其次，利用该自组装模板，形成基于静电和配位相互作用的杂化纳米结构。研究了超分子杂化结构对其形状和内部结构的影响。组件的尺寸控制可以在60-420纳米的范围内。通过控制不同非共价相互作用的组合来指导自组装和模板化的前景，有可能为各种应用创建量身定制的系统。
A novel concept for the formation of organic–inorganic hybrid nanostructures based on a tunable supramolecular templating mechanism involving several types of noncovalent interactions is presented. Different organic–inorganic hybrid structures with narrow size distributions composed of a cationic dendrimer, an oppositely charged divalent diazo dye, and CdS can be created: First, larger supramolecular structures consisting of several 100 to 1000 dendrimers is built based on ionic and π–π interaction. Second, with this self-assembled template, the hybrid nanostructure forms based on electrostatics and coordination interaction. The influence on shape and internal structure of the supramolecular hybrid architectures was investigated. A size control of the assemblies is possible in a range of 60–420 nm. The prospect to direct self-assembly and templating through the controlled combination of different noncovalent interactions potentially allows to create tailor-made systems for various applications.
