Methods of metal-catalysed polymerisation are described using a metal catalyst of formula (III): wherein Rin each occurrence is independently selected from Calkyl and aryl that may be unsubstituted or substituted with one or more substituents; y is 0 or 2; and Zis an anion. Methods described include Buchwald-type and Suzuki-type polymerisation.

Method of forming polymers

A composition suitable for use in an organic light-emitting layer () of an organic light-emitting device having an anode () and a cathode (), the composition comprising a fluorescent light-emitting material, a first triplet-accepting material and a second triplet-accepting material that is different from the first triplet-accepting material. The fluorescent light-emitting material may be a repeat unit of a light-emitting polymer, and the first and second triplet-accepting materials may independently be repeat units of the light-emitting polymer or may be mixed with the fluorescent light-emitting material.

Organic light-emitting compositions having multiple triplet-accepting materials, and devices and methods thereof

Methods of metal-catalyzed polymerization are described using a metal catalyst of formula (III): wherein Rin each occurrence is independently selected from Calkyl and aryl that may be unsubstituted or substituted with one or more substituents; y is 0 or 2; and Zis an anion. Methods described include Buchwald-type and Suzuki-type polymerization.

A non-carcinogenic process for the activation of zinc metal in a medium polarity solvent, wherein said zinc metal is activated by the reaction thereof with a halogen and a lithium compound selected from lithium halides and lithium pseudohalides, the use of said activated zinc metal for the preparation of an organozinc halide of formula R&#x2014;ZnX, and a process for the preparation of compounds obtainable by the reaction of said organozinc halide of formula R&#x2014;ZnX with compounds having functionality enabling them to react with said organozinc halide.
