A process for the preparation of a material capable of luminescence, said material 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 the nature, location and/or proportion of the polymer or oligomer and of the organometallic group in the material are selected so that the luminescence predominantly is phosphorescence; said process comprising:
(a) reacting monomers to form a polymer or oligomer wherein each monomer has at least two reactive groups selected from the group consisting of a halide group, a boronic acid group, a boronic ester group and a borane group and each monomer comprises an aryl or heteroaryl group; and
(b) terminating the polymer or oligomer formed in step (a) using an end-capping reagent, said end-capping reagent comprising one reactive group selected from the group consisting of a halide group, a boronic acid group, a boronic ester group and a borane group and either (i) containing an organometallic or (ii) being capable of forming a complex with a metal when treated with a metal-complexing reagent; and
(c) where the end-capping reagent is as defined in (ii), treating the terminated polymer or oligomer from step (b) with a metal-complexing reagent. |
