The present invention relates to a compound of the formula (l): [Z-L]MQn (l) wherein Z represents a metal cation selected from the group consisting of palladium, platinum or gold or mixtures thereof; L is a tetradentate polypyridyl ligand of the general formula N-N'-N'-N (II) bonded to to Z to form a complex Z-L: wherein group X may independently represent a bridging group connecting two adjacent pyridyl groups, and may be an optionally substituted amino group, an optionally substituted methylene group, carboxyl or sulfoxyl group, a sulphur atom, or an oxygen atom; wherein group Y may be as X, or may independently represent two hydrogen atoms, halogen atoms, optionally substituted alkyl groups, optionally substituted aryl groups, optionally substituted allyl groups, optionally substituted ester groups, optionally substituted ether groups; M is an integer representing the positive charge of the Z-L complex; Q. represents a counter anion ionically bonded to the Z-L complex; and n is an integer representing the number of counter anions ionically bonded to the Z-L complex; and R, R', R" and R'" independently represent one or more hydrogen atoms, halogen atoms, hydroxide, carboxylic acid, optionally substituted alkyl groups, optionally substituted aryl groups, optionally substituted allyl groups, optionally substituted ester groups, optionally substituted ether groups, or R, R', R" and R'" represents a monocyclic or bicyclic aliphatic or aromatic structure with one pyridyl groups, or two groups R, R', R" and R'" may together form a tricyclic structure with two adjacent pyridyl groups, and Riv and Rv may represent a carbon-carbon bridge between two adjacent pyridyl groups, or in the case wherein Z and Y are both linking two pyridyl groups, may each individually represent a hydrogen atom, a halogen atom, an optionally substituted alkyl group, and an optionally substituted ether group.
