Abstract:
A titanium-oxo-chelate catalyst formulation, comprising: (i) at least one compound of the formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11 and R12 independently of each other are for example hydrogen, halogen, C1-C20alkyl, C6-C14aryl which is unsubstituted or substituted; or R1, R2 and R3 and/or R4, R5 and R6 and/or R7, R8 and R9 and/or R10, R11 and R12 together with the C-atom to which they are attached each form a C6-C14aryl group which is unsubstituted or substituted; or R1 and R2 and/or R4 and R5 and/or R7 and R8 and/or R10 and R11 together with the C-atom to which they are attached form a 5- to 7-membered carbocyclic ring; at least one chelate ligand compound of the formula (IIa), (IIb) or (IIc), wherein R1, R2, R3, R4, R5 and R6 are defined as above for formula (I), is suitable as a photolatent catalyst formulation for polymerizing compounds, which are capable to crosslink in the presence of a Lewis acid.
Abstract:
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.
Abstract:
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.
Abstract:
The present invention discloses functionalized nanoparticles comprising on the surface a covalently bound radical of the formula (I) wherein the nanoparticles are SiO2, Al2O3 or mixed SiO2 and Al2O3 nanoparticles, and wherein the general symbols are as defined in claim 1. 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.
