Photo-latent titanium-oxo-chelate catalysts

The present invention relates to compounds of formula (I), a process for their production and their use in electronic devices, especially electroluminescent devices. When used as electron transport and/or host material for phosphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices. 

4H-imidazo[1,2-a]imidazoles for electronic applications

Functionalized nanoparticles, which are obtainable by combining in a first step a functionalized dyestuff, a silicon-based spacer and a catalyst, and in a second step reacting the product obtained in the first step with a co-reactive organic silicon, aluminum, zirconium or titanium compound. Optionally, the thus obtained functionalized nanoparticles can be combined or encapsulated with a polymer. The functionalized nanoparticles are useful as colorants and fluorescents in plastics, paints, inks, electronic materials, cosmetic articles, and the like.

Functionalized core-shell nanoparticles

The present invention provides photolatent Ti-chelate catalyst compounds of formula (I), wherein Ris for example C-Caryl which is substituted by one or more R', R&#x2032;or R&#x2032;; or the two Rtogether are unsubstituted linear or branched C-Calkylene; R, R, R, R&#x2032;, R&#x2032;, and R&#x2032;independently of each other are for example hydrogen, halogen or linear or branched C-Calkyl; R, Rand Rindependently of each other are hydrogen, linear or branched C-Calkyl, C-Caryl, Br or Cl, provided that not more than one of R, Rand Ris hydrogen; as well as formulations comprising said compounds and defined 1,3-diketones. 

Photo-latent titanium-chelate catalysts

The present invention discloses functionalized nanoparticles comprising on the surface a covalently bound radical of the formula (I) wherein the nanoparticles are SiO, AlOor mixed SiOand AlOnanoparticles, and wherein the general symbols are as defined in claim. These functionalized nanoparticles are for example useful as stabilizers and/or compatibilizers in organic materials, or as photoinitiators in pre-polymeric or pre-crosslinking formulations, or as reinforcer of coatings and improver of scratch resistance in coating compositions for surfaces. 

Functionalized nanoparticles

The invention relates to novel colorants based on bismuth oxyhalide and bismuth oxycarboxylates, bismuth oxyenolates or bismuth oxysulfonates and to the use thereof as pigments and coating agents. They are preferably solid solutions, especially solid solutions mainly in the tetragonal crystal lattice of bismuth oxyhalide.
