Vm. Mukkala et al., SYNTHESIS AND LUMINESCENCE PROPERTIES OF SOME EU(III) AND TB(III) CHELATE LABELS HAVING 2,2' 6',2''-TERPYRIDINE AS AN ENERGY ABSORBING PART/, Journal of alloys and compounds, 225(1-2), 1995, pp. 507-510
A series of luminescent 2,2':6',2 ''-terpyridine lanthanide chelates,
in which the group needed for coupling to bioactive molecules is situa
ted in the chelating part of the molecule, was synthesized. The lumine
scence properties of the labels both as free activated chelates and af
ter coupling to proteins were also studied.
