Abstract
Official abstract text for this publication.
A material capable of luminescence comprising a polymer or oligomer and an organometallic group, wherein the polymer or oligomer is at least partially conjugated and the organometallic group is covalently bound to the polymer or oligomer and at least one of the nature, location, and proportion of the polymer or oligomer and of the organometallic group in the material are selected so that the luminescence predominantly is phosphorescence.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing a material capable of luminescence, wherein the luminescence predominantly is phosphorescence, said material comprising a polymer or oligomer and an organometallic group, the organometallic group being covalently bound to the polymer or oligomer only at end-capping positions of the polymer or oligomer, wherein the organometallic group is present in the material in an amount between 1 weight percent and 10 weight percent; said pro…
