A microencapsulated catalyst-ligand system is provided comprising a catalyst and a ligand microencapsulated within a permeable polymer microcapsule shell, wherein the ligand is a polymeric ligand. Processes for the preparation of said microencapsulated catalyst-ligand system are also provided.

Microencapsulated catalyst-ligand system

There is provided a process for removing metal from solution wherein a solution comprising a metal is contacted with a scavenger support, whereby the scavenger support binds to at least some of the metal in solution thereby decreasing the amount of metal in solution, characterized in that the scavenger support comprises a functionalized support comprising pendant groups selected from 1,3-ketoesters or 1,3-ketoamides or mixtures thereof attached to a support wherein a number of the pendant groups are reacted with an amine. Scavenger supports comprising a functionalized support comprising pendant 1,3-ketoester or 1,3-ketoamide groups of formula 1: wherein Ris an optionally substituted hydrocarbyl, perhalogenated hydrocarbyl or heterocyclyl group; X is O or NR, wherein the free valence of O or NRis bonded to a support optionally via a linker; and Ris hydrogen, an optionally substituted hydrocarbyl, or heterocyclyl group, wherein a number of the pendant groups are reacted with an amine are also provided. Preferred scavenger supports include scavenger supports comprising pendant 3-iminoesters, 3-iminoamides, 2,3-enaminoesters or 2,3-enaminoamides pendant groups of Formula (3) or (4): wherein Ris an optionally substituted hydrocarbyl, perhalogenated hydrocarbyl or heterocyclyl group; X is O or NR, wherein the free valence of O or NRis bonded to a support optionally via a linker; Ris hydrogen, an optionally substituted hydrocarbyl, or heterocyclyl group; Ris a substituent group; and Ris hydrogen or a substituent group, or Rand Rmay optionally be linked in such a way so as to form an optionally substituted heterocyclic ring, or tautomers or salts thereof.

Scavenger supports and the use thereof in a process for the extraction of metals

The present invention relates to compounds and their use as ligands, in particular, in metal catalyst complexes. The ligands of the invention are capable of binding to a solid support. The invention includes the ligands in their own right and when bound to a support and the compounds may be used to prepare metal catalyst complexes.

Compounds for use as ligands

A scavenger support and a process for removing metal from solution by contacting the solution with the scavenger support, whereby the scavenger support binds to at least some of the metal in solution thereby decreasing the amount of metal in solution. The scavenger support is a functionalised support having pendant groups selected from 1,3-ketoesters or 1,3-ketoamides or mixtures thereof having a structure according to formula 1, wherein a number of the pendant groups are reacted with an amine: wherein Ris an optionally substituted hydrocarbyl, perhalogenated hydrocarbyl or heterocyclyl group; X is O or NR, wherein the free valence of O or NRis bonded to a support optionally via a linker; and Ris hydrogen, an optionally substituted hydrocarbyl, or heterocyclyl group.

The present invention relates to phosphorescent copolymers comprising trifunctional triplet emitters. The polymers according to the invention are highly soluble, readily accessible synthetically and more suitable for use in organic light-emitting diodes than are comparative materials in accordance with the prior art.

Electroluminescent polymers

The present invention relates to novel conjugated polymers comprising spirobifluorene units and their use in optoelectronic devices, preferably in, for example, displays based on polymeric organic light-emitting diodes.

Conjugated polymers containing spirobifluorene units and the use thereof

The present invention relates to solutions and/or dispersions of organic semiconductors in a solvent mixture of at least two different organic solvents, characterized in that

Solutions and dispersions of organic semiconductors

The present invention relates to solutions of organic semiconductors and their use in the production of electronic components.

Solutions of organic semiconductors that contain additives

The invention relates to the preparation of aryl-aryl coupled compounds and materials. These materials play an important role in industry, for example as liquid crystals, pharmaceuticals and agrochemicals, to mention just a few application areas. These compounds, in particular, are also of major importance especially in the high-growth area of organic semi-conductors (for example, applications in organic or polymeric light-emitting diodes, organic solar cells, organic ICs).
