Functional columnar liquid crystalline phases from ionic complexes of dendronized polymers and sulfate alkyl tails

Canilho, Nadia ; Kasëmi, Edis ; Schlüter, Dieter A. ; Ruokolainen, Janne ; Mezzenga, Raffaele

In: Macromolecular Symposia, 2008, vol. 270, no. 1, p. 58 - 64

We describe how cationic dendronized polymers of generations 1, and 2 and anionic monoalkyl tails can be combined by supramolecular ionic complexation into comb-like liquid crystalline polymers. The final structures in bulk of these supramolecular complexes were studied by differential scanning calorimetry (DSC), cross-polarized optical microscopy (CPOM), small angle x-rays scattering (SAXS) and...

Real space imaging and molecular packing of dendronized polymer-lipid supramolecular complexes

Canilho, Nadia ; Kasëmi, Edis ; Schlüter, Dieter A. ; Ruokolainen, Janne ; Mezzenga, Raffaele

In: Macromolecules, 2007, vol. 40, no. 21, p. 7609 -7616

The present work describes the molecular structure and the topology in real space of self-assembled comblike liquid crystalline polymers based on supramolecular ionic complexation of dendronized polymers and lipids. The molecular organization was studied as a function of the generation of the dendronized polymers and the length of the lipid tails, both parameters being known to strongly influence...
