A cationic dendritic molecule that has alkyl chains has been synthesized and employed to encapsulate anionic polyoxometalates through electrostatic interactions. The prepared surfactant-encapsulated polyoxometalate (SEP) complexes were used as building blocks to fabricate self-assemblies in solution and the solid state. Monodispersion, lamellar, and columnar assemblies of SEP complexes have been characterized in detail. With increasing the number of peripheral cationic dendrons on inorganic clusters, the SEPs undergo changes from globular assemblies to monodispersions in solution and from lamellar assemblies to hexagonal columnar structures in the solid state, depending on the amounts of cationic dendrons in the complexes. The structural evolvement was simulated through consideration of the size and shape of the cationic dendron and polyanionic clusters, and the experimental results are in good agreement with the interpretation of the simulations. The present research demonstrates a new kind of dendritic complex and provides a route for controlling their assembling states by simply alternating the number of cationic dendrons in the complexes.

“…For the preparation of the tpy core-functionalized side dendritic wedges we etherified the dendritic benzyl bromide 6 [11] with OH-Ph-tpy 1 (Scheme 3, Figure 2). The particular alkoxy-decorated second-generation dendron 6 was employed in order to confer solubility to the final metal-containing polymeric systems and, more importantly, for future correlations with some analogous dendronized polyethers that had been found to present interesting self-organizational solid-state patterns.…”

This paper reports the synthesis of side chain dendritic polymers by a newly developed "attachment through coordination" methodology. Initially, aromatic/aliphatic polyethers bearing two uncomplexed terpyridine (tpy) groups per repeating unit are prepared, and dendritic fragments corefunctionalized with tpy-Ru III Cl 3 moieties are afterwards attached onto these free tpy side groups. The two second-generation alkoxy-decorated side dendrons employed here provided solubility in the final polymeric system and potential for the development of ordered structures. Selective complexation between terpyridines and ruthenium ions proved

“…More Scheme 19. i) NaH, THF, 20°C interestingly, amphiphilic star copolymers 90 having four hydrophobic oligoether dendritic groups at the periphery and four internal hydrophilic PEG chains show conformational switching from one solvent system to another [49]. Surfactant-like amphiphilic oligoether-based dendrimers 91 bearing long alkyl chains on the surface and a polar focal point functional group can form stable monolayer at water surface [50]. The structurally "inverted" dendrimers 92, having multi-hydrophilic head groups on the surface and a non-polar focal point functional group, also behave in a similar manner [51].…”
