Abstract
In the frame of the project we are going to investigate the synthesis and properties of self-organized supramolecular polyurethanes, formed through a molecular recognition process of complementary polyurethane units and low molar mass proton donors. The aim of the present research is to establish the correlations between the structure of both polyurethane and proton donor and the properties of self-organized supramolecular polyurethanes with a special emphasis on the stability of liquid crystalline phases. Namely, understanding the effects of structural features on the stability of self-organized liquid crystalline polymeric systems (micro-properties) is a key factor for reaching the designed and desired macro-properties of these materials. Stability of supramolecular side-chain liquid-crystalline polymers depends on the strength of noncovalent interactions and on the structure of individual polymer and low molar mass components. To study these influences we will (i) synthesize polyurethanes with proton acceptor pyridine groups in the polymer main-chain (2,6-bis-(hydroxymethyl)-pyridine) or side-chain (stilbazole) and (ii) prepare supramolecular polyurethane complexes from the synthesized polyurethanes and appropiate low molar mass proton donors with carboxylic and phenolic groups (4-alkoxybenzoic acids, cholesteryl hemisuccinate, phenolic derivatives). We will also estimate the possibility to use the novel supramolecular polyurethanes for optical displays.
