Abstract :
The interaction of water with poly-p-phenylene vinylene is investigated theoretically by means of quantum-chemical calculations on molecular model systems. Water is found to form van der Waals complexes characterized by hydrogen-like bonds with the protons and/or the π system of the PPV chain. The formation of such complexes can lead to significant conformational changes which, in turn, affect the electronic properties of the conjugated polymer.
