The invention provides a compound of formula (I): wherein: R1 is an optionally substituted 2-(1-azathiaxanthone); each -R2 is independently of the formula -CH2-C(=O)-R4, wherein R4 is an amino acid or a salt thereof, attached to the remainder of R2 through the nitrogen atom of the amino group; and R3 is hydrogen or a C1-6 alkyl group); or (wherein: R1 is an optionally substituted 2-(1-azaxanthone); each R2 is independently an optionally substituted glutaric or succinic acid, or a salt or ester thereof; and R3 is hydrogen or a C1-6 alkyl group).
The invention provides a compound comprising a xanthone or thiaxanthone sensitising moiety, capable of coordinating to a lanthanide ion by the nitrogen atom of an integral pyridyl group or a related group able to bind a lanthanide ion.
