Preliminary investigations show that these materials are potential candidates for use in organic light-emitting devices (OLEDs). Two types of OLEDs were fabricated: single layer (SL) and single heterostructure (SHS), with poly(p-phenylenevinylene) (PPV) as hole transporting layer. Our best results were obtained with single layer device emitting green light with a luminance of 0.18 cd m(-2) and 0.24 cd m(-2) at a driving voltage of 10 V. (c) 2004 Elsevier B.V.

Then, water-soluble hydroxyaluminium phthalocyaninesulfonate [Al(OH)Pc(SO3Na)(1-2)] was deposited by casting. The cell ITO/PMPSi/AI(OH)Pc(SO3Na)(1-2)/Al showed non-linear current- voltage characteristics. For applied voltages higher than 10 V, polarized electroluminescence was observed. Its spectral characteristic consisted of two peaks with maxima at about 320 and 700 nm; their polarized anisotropies R-EL = Phi(parallel to) / Phi(perpendicular to) were ca. 15 and 0.5, respectively}, language = {en} } @article{StillerKoepnickMuzikanteetal.1999, author = {Stiller, Burkhard and K{\"o}pnick, Thomas and Muzikante, I. and Neilands, O. and Utinans, M. and Dubrovich, O. and Karageorgiev, Peter and Brehmer, Ludwig}, title = {Optically induced switching effect of polymer containing indandione-1,3-pyridinium betaine side chains}, issn = {0378-2271}, year = {1999}, language = {en} } @article{StillerKarageorgievPerezetal.2000, author = {Stiller, Burkhard and Karageorgiev, Peter and Perez, E. and Valez, M. and Reiche, J{\"u}rgen and Prescher, Dietrich and Dietzel, Birgit and Brehmer, Ludwig}, title = {Scanning kelvin microscopy as a tool for visualisation of optically induced molecular switching in azobenzene self assembling films}, issn = {0142-2421}, year = {2000}, language = {en} } @article{StillerKarageorgievBuchsteineretal.2003, author = {Stiller, Burkhard and Karageorgiev, Peter and Buchsteiner, Andrea and Geue, Thomas and Henneberg, Oliver and Brehmer, Ludwig and Natansohn, Almeria and Hollricher, Olga}, title = {Using light as a tool : optically Induced mass transport generated in Near-Fields}, issn = {0038-7355 -}, year = {2003}, language = {en} } @article{StephanSchraderBrehmer2000, author = {Stephan, J{\"o}rg and Schrader, Sigurd and Brehmer, Ludwig}, title = {Monte Carlo simulations of charge transport in molecular solids : a modified Miller Abrahams type jump rate approach}, year = {2000}, language = {en} } @article{StephanLiemantAlbrechtetal.2000, author = {Stephan, J{\"o}rg and Liemant, Alfred and Albrecht, Fred and Brehmer, Ludwig}, title = {Interplay of polaronic and disorder effects on electronic charge transport}, year = {2000}, language = {en} }
