The present invention provides a metal cluster complex of formula (lla) having the formula [M 6 Q 8 L 6 ], optionally together with a counter ion, where each M is a metal atom selected from Re, Mo and W; each Q is independently selected from a halogen or chalogen atom; and each L is a ligand, and at least one ligand L is U, where L' has an aromatic group and a polymerizable functionality. Also provided is a polymerizable composition comprising the metal cluster complex of formula (lla) and a polymer obtained or obtainable from the polymerization of the polymerizable composition. Also provided is a method of generating light, the method comprising the steps of providing an octahedral metal cluster complex of formula (I), and applying an electric field across the metal cluster complex at a voltage of 5 V or more, to generate light from the cluster, wherein the cluster complex (I) has the formula [M 6 Q 8 L 6 ], optionally together with a counter ion, where each M is a metal selected from Re, Mo and W; each Q is independently selected from a halogen atom or a chaicogen atom; and each L is a ligand. |
