Effect of solid-state structure on optical properties of conjugated organic materials

Autor: U Stalmach, Georges Hadziioannou, Victor V. Krasnikov, Paul F. van Hutten, Hendrik-Jan Brouwer, Lahoussine Ouali

Publikováno v: Synthetic Metals, 102(1-3), 1443-1446. Elsevier Science

Luminescence from PPV derivatives and related conjugated polymers in the solid state is strongly subject to intermolecular interactions. Model systems of oligomers have been investigated to explore such interactions in more detail. Direct electronic

Electrochemiluminescence of conjugated polymer

Autor: Andrew B. Holmes, Umamaheswari Janakiraman, Danilo Dini, Rainer E. Martin, Albrecht Preusser, Karl Doblhofer

The mechanism of charge transport in the conducting polymer (CP) MEH-PPV is analysed by conducting the electrogenerated chemiluminescence (ECL) experiment and simulating the ECL transients.

Synthesis and self-organization of PPV-based block copolymers for photonic applications

Autor: U Stalmach, B. de Boer, Georges Hadziioannou, Christian Melzer

Publikováno v: Synthetic Metals, 121(1-3), 1541-1542. Elsevier Science

Rod-coil block copolymers have been synthesized with the objective of enhancing the photovoltaic efficiency by the incorporation of both donor and acceptor components in a molecular architecture that is self-structuring. Block copolymers were obtaine
