Novel thermolatent bases and their use as catalysts for the preparation of polyurethanes or epoxy resins are disclosed herein. A process for the preparation of polyurethanes or epoxy resins in the presence of the catalyst is also disclosed.

Catalyst for the preparation of polyurethanes

The present invention relates electroluminescent devices, comprising a compound of the formula especially as host for phosphorescent compounds. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.

Heterocyclic bridged biphenyls

The present invention relates to the use of a composition comprising specific a-amino-ketones, HO, a HOprecursor or a peracid and optionally an activator as a bleaching mixture for textile materials or dishes either manually or in an automatic washing machine or dish washer. Further aspects of the invention are the composition comprising specific a-aminoketones and HO, a HOprecursor or a peracid and a process for bleaching of stains or of soiling on textile materials or dishes in the context of a washing process either manually or in an automatic washing machine or dish washer. Also aspects of the invention are detergent formulations comprising such a composition and novel compounds.

Metal free bleaching composition

The present invention relates to specific acylhydrazone compounds, their use as oxidation catalysts and to a process for removing stains and soil on textiles and hard surfaces. The compounds are substituted with a specific cyclic ammonium group adjacent to the acyl group. Further aspects of the invention are compositions or formulations comprising such compounds.

Bleach catalysts

The present invention relates to compounds of the formula (I), a process for their preparation and their use in organic light emitting diodes (OLEDs), especially as host for phosphorescent compounds. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or special characteristics of electroluminescent devices.
