“…In comparison with the linear analogous, dendrimers show that the solubility is significantly increased. Due to the accessibility of the peripheral groups by globular shape, the reactivity and solubility can be controlled by the type of the peripheral groups 32,33,[37][38][39] .…”

“…5 In particular, branched polymers have been studied as a counterpart to linear polymers to identify distinct physical behavior. 6 As representative branched examples, dendrimers and dendrons (sections of dendrimers) have well-defined tree-like chain structures with lowmolecular-weight distributions. Because of their refined structural features, they have been used as useful macromolecular building blocks for functional materials.…”

This paper reviews our recent research with regard to bulk self-assemblers based on well-defined branched building blocks. Branched molecules/polymers have been known to show different physical properties from conventional linear-shaped polymers. As well as thermal and solution properties, structural modification into branched building blocks also has a significant influence on self-assembling behavior in the bulk states, including solid and liquid crystalline (LC) phases. As a branched component, dendrons/dendrimers with well-defined structures can be ideal candidates for the construction of advanced self-assemblers. Recently, we worked on new assembling systems such as dendron-coils, block codendrimers and discotic LC molecules. In the design, we used aliphatic polyether dendrons in most cases and poly(benzyl ether) dendrons in part. Their bulk assembling and thermal properties were found to be distinct from conventional linear block copolymers and they were dependent upon their chain architectures. To self-assemble into ordered nanostructures, the hybrid assembers were designed to have incompatible blocks, for example, hydrophilic and hydrophobic parts. Furthermore, in some cases an ionic complexation was carried out to maximize the immiscibility between the two different blocks. This review describes the molecular manipulations to engineer the nanoassemblies in bulk and also the ionic transportation properties depending on the assembling morphology.

“…Several intriguing properties, such as low solution viscosity and high solubility compared with linear polymers, have been described for these poly-mers. 9,10 Hyperbranched polymers have especially been considered for material consuming applications because they are more easily produced in larger scale compared with dendrimers. Several applications such as rheological additives 11 and toughening agents 12 have been suggested for hyperbranched polymers.…”

A research area that has obtained increasing interest during the last decade concerns improvement of macromolecular properties by changes in the macromolecular architecture. One group of these materials is dendritic polymers, which are highly branched structures exhibiting very different properties compared with linear polymers. One potential application for these polymers is as radiation curable thermoset resins. This article describes a study where the use of an aliphatic hyperbranched polyester as a base for new radiation curable thermoset resins. The hyperbranched polyesters have been characterized with respect to cure rate and final mechanical properties compared with conventional resins. It is shown that hyperbranched polyesters can be used as versatile scaffolds for various radiation curable resin structures.
