The present invention relates to a compound of formula (I), wherein R, R, Rand Rare each independently hydrogen or R, with proviso that a pair of two substituents selected from Rand R, Rand R, and Rand Ris linked to one another and forms a group of formula (II); a material for an organic electroluminescence device comprising at least one compound of formula (I); an organic electroluminescence device which comprises an organic thin film layer be-tween an anode and a cathode, wherein the organic thin film layer comprises one or more layers and comprises a light emitting layer, and at least one layer of the organic thin film layer comprises at least one compound of formula (I); and an electronic equipment comprising the inventive organic electroluminescence device. 

Specific ladder type compounds for organic light emitting devices

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 present invention relates to a block copolymer prepared by ATRP, wherein the polymer chain terminal group is structurally modified with the functionally effective group of a lubricant or polymer additive selected from the group consisting of antioxidants, metal deactivators, antiwear and extreme pressure additives and corrosion inhibitors. The invention also relates to a composition comprising the structurally modified block copolymer and a composition of matter subject to oxidative, thermal or light induced degradation, such as lubricants or polymers.

Polymers produced by atom transfer radical polymerisation technique with structurally modified terminal groups

The invention relates to &#x3b1;-halocarboxylic acid esters of polyhydric, at least trihydric, alcohols, which can be used as initiators for ATRP. Using those initiators it is possible to prepare block copolymers having branched structures.

&#x3b1;-Halogenated acid esters with polyvalent alcohols as atom transfer radical polymerization initiators

The invention relates to comb polymers and macromonomers based on acrylates prepared by the ATRP (Atom Transfer Radical Polymerization) method. These polymers have an improved capability of dispersing pigments in the given solvent. The invention also relates to compositions comprising the comb polymers and macromonomers dispersible inorganic or organic pigment particles. The compositions are used by applying them to any suitable substrate, for example to metal, wood plastic or ceramic materials.
