Journal ArticleDOI
Solid-state dye-sensitized mesoporous TiO2 solar cells with high photon-to-electron conversion efficiencies
Udo Bach,D. Lupo,Pascal Comte,Jacques-E. Moser,F. Weissörtel,Josef Salbeck,H. Spreitzer,Michael Grätzel +7 more
TL;DR: A dye-sensitized heterojunction of TiO2 with the amorphous organic hole-transport material 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′-spirobifluorene (OMeTAD) was described in this article.
Journal ArticleDOI
Low molecular organic glasses for blue electroluminescence
TL;DR: In this paper, a two-layer blue electroluminescence device with high color purity, high brightness and low turn-on voltage is presented, which is fabricated by combining a hole transporting spiro-TAD with an electron transport spiro PBD.
Journal ArticleDOI
White Light Emission from Organic LEDs Utilizing Spiro Compounds with High‐Temperature Stability
F. Steuber,J. Staudigel,M. Stössel,J. Simmerer,Albrecht Winnacker,Hubert Spreitzer,F. Weissörtel,Josef Salbeck +7 more
Journal ArticleDOI
Solid‐State Amplified Spontaneous Emission in Some Spiro‐Type Molecules: A New Concept for the Design of Solid‐State Lasing Molecules
Nicklas Johansson,Josef Salbeck,J. Bauer,F. Weissörtel,P. Bröms,Annica Andersson,William R. Salaneck +6 more
TL;DR: In this paper, the spectral narrowing in submicron thick neat films, of 2,2′,7,7′-tetraphenyl-9,9′-spirobifluorene (spiro-quarterphenyl) and 2, 2′, 7,7-7′ -tetrakis(biphenyl 4-yl)-9, 9-spira-biflourene (Spiro-sexiphenYL), was investigated.
Journal ArticleDOI
Spiro linked compounds for use as active materials in organic light emitting diodes
TL;DR: Spiro-linkage of low molecular weight entities as a new structural concept for the design of new active materials for electroluminescent applications is presented in this article, which results in nonpolymeric organic glasses with high thermal stability as can be derived from their high glass transition temperatures.
