Abstract
Re-containing cluster complexes have been developed and polymerised to generate photo/electroluminescent materials, which can be used to construct PLEDs.

INTRODUCTIONInorganic-organic hybrids based on photoluminescent octahedral clusters [{ } ] (where M is Mo, W or Re; Q – inner ligands that are either halogens or chalcogens and L are various outer ligands) are an attractive, new class of materials.-18 They offer the opportunity to combine the excellent photoluminescent properties of octahedral cluster complexes (i.e. long living photoluminescence in the red/near-infrared region (NIR) with high quantum yields) with some useful properties conferred by the organic components

Upon coordination of 4-vinylbenzoic acid the signals from the aromatic ring protons are shifted to lower field in the 1H NMR spectra in comparison with those from the free acid. 1H NMR showed that during the reaction some trans to cis isomerisation occurred producing less than 5 % of the cis-isomer (Figure S1 in Electronic Supplementary Information)
Summary
Inorganic-organic hybrids based on photoluminescent octahedral clusters [{ } ] (where M is Mo, W or Re; Q – inner ligands that are either halogens or chalcogens and L are various outer ligands) are an attractive, new class of materials.-18 They offer the opportunity to combine the excellent photoluminescent properties of octahedral cluster complexes (i.e. long living photoluminescence in the red/near-infrared region (NIR) with high quantum yields) with some useful properties conferred by the organic components. They may exhibit new properties that are not found in the individual components. Fluorescent dyes or phosphorescent dopants 24, 25 are used widely in combinations with PVK in polymer organic light-emitting diodes (PLEDs) to improve device efficiency 26-29 or to tune the colour.[30, 31] we have designed PLEDs employing a -PVK-based hybrid material and studied their electroluminescent properties
