Formation of CdS in Supramolecular Dendrimer-Dye Assemblies: Electrostatic and Electrostatic-Coordination Templating
A novel concept for the formation of organic inorganic hybrid nanostructures based on a tunable supra-molecular 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 pi-pi 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.
