The convergent synthesis of a new class of chiral dendrimers is described. Owing to their structural resemblance to depsipeptides they are called depsipeptide dendrimers. The ex-chiral pool synthesis starts from (R,R)-, (S,S)-, and meso-tartaric acid as branching units and dipeptides or tripeptides consisting of glycine, (L)-alanine, and (L)-leucine as

Dendrimers are a class of synthetic macromolecules that bridge the gap between polymers and small molecules. The dendritic structure provides both the possibility for compartmentalization of reagents as well as offering a multivalent surface, and they are in that respect similar to globular proteins.

Chemistry - A European Journal, 2000
The first five generations of the stilbenoid dendrimers 1(n) (n = 1-5) have been prepared by a combined coupled synthesis (between the generations of the dendrons 8-12) and convergent synthesis. Wittig-Horner reactions together with a protecting group technique yield monodisperse compounds of high constitutional and configurational purity.

A convergent synthesis in which all trans double bonds were constructed by Wittig-Horner reactions produces dendrimers of the general structure 1. With long-chain alkoxy residues on the periphery of the benzene rings, the first two generations display liquid crystalline behavior.

Supramolecular formations of antibodies by their specific molecular recognition to antigens are investigated. Linear and network supramolecular architectures have been constructed by using immunoglobulin G (IgG) and divalent or trivalent antigens, respectively.

Tree-like dendrimers with decreasing number of chromophores from periphery to core is an attractive candidate for light-harvesting applications. Numerous dendritic designs with different kinds of light-collecting chromophores at periphery and an energy-sink at the core have been demonstrated with high energy transfer efficiency.

The synthesis, properties, and potential applications of rotaxane dendrimers, dendritic molecules containing rotaxane-like mechanical bonds to link their components are described. Rotaxane dendrimers are classified into three types depending on where rotaxane-like features are introduced - Type I, II, and III rotaxane dendrimers which incorporate ...

In this chapter dendrimer basics are reviewed. It is impossible to describe, refer to or even list the related literature (our "dendrimer" database consists of over 7,000 papers and patents), thus selection of references has been made based on personal preference, often choosing clarity over details and overarching principles instead of detailed ...
