The invention relates to a coordination complex system comprising a ligand
having at least two donor moieties, which are complexed to at least a
metal selected from a transition metal and lanthanide, characterized in
that the ligand comprises at least two building blocks, each having at
least one functional group and at least one donor moiety, wherein one
building block is non-covalently bonded through its functional group to a
complementary functional group of another building block or of a
template, wherein the template comprises at least one other functional
group that is noncovalently bonded to a complementary functional group of
another building block, and wherein all building blockemplate-building
block structures are the same when the template contains more than two
functional groups.
