Poly Benzyl Ether Dendrons Carrying Flexible Alkyl Chains

Poly(Benzyl Ether) Dendrons Carrying Flexible Alkyl Chains 

For fundamental aspects as well as for potential applications, it is of interest to 

Considering a hexagonal close compact packing of the C,so spheres along the columnar axis, surrounded by the flexible dendritic shell, the number of molecules included in an elementary columnar slice (8.7 A thick) was calculated. From the values of the lattice parameters and the estimated molecular volumes (4550 and 4700A for 15 and 16, respectively), this number turned out to be about ten for each compound. The supramolecular organization thus results in bundles of ten dendrimers superimposed one over the other to form an elliptic columnar core, 

To further investigate the formation of columnar phases, methanofuUerenes carrying simultaneously at both extremities either two identical poly(benzyl ether) 

essentially all the malonate and fullerene derivatives equipped with such flexible poly(benzyl ether) dendrons give rise to columnar phases, and their supramolecular organization within the columnar phases is governed by the dendrimer, providing that the size of the dendritic addends is large enough to compensate and circumvent the large area of the bulky C .
