A light emitting device comprising: an anode; a cathode; a light emissive layer located between the anode and the cathode, said light emissive layer comprising a charged metal complex for emitting light and a counterion or counterions with sufficient charge to balance the change on the charged metal complex; characterized in that the counterion or counterions are substantially immobile so (that light output from the device is immediate, provided that the combined charged metal complex and counterion do not have General Formula: (I) or (II); where C&#x2014;N is a cyclometallated liquid.

Light-emitting device

A process for modifying at least one dendron that is intended to form part of a dendrimer is disclosed. One reacts at least one reactable unsaturated group in a chemoselective manner to form a less unsaturated group. Also disclosed is a process for modifying dendrimers in a similar manner.

Reactive organometallic dendrimers

Reactive dendrimers

A light emitting device comprising at least one compound of formula (I), (II) or (III) wherein Rand R, which may be the same or different, are organic substituents not including H, and wherein Rand Rare each independently selected from halo and organic substituents not including H, and wherein R, R, R, R, R, and Rare each independently selected from H, halo, and organic substituents, wherein any two or more of R, R, R, R, R, R, R, R, R, and Rmay optionally be fused together to form a ring system, provided that one of Rand Ris not part of a fused ring system, and provided that Rand Rare not fused to each other to form a ring system, and wherein one but not both of either (a) Rand R, or (b) Rand R, are fused to each other to form a ring system.
