The invention concerns a method for preparing a particle comprising a lanthanide chelate, comprising polymerizing a lanthanide chelate derivative with one or more monomers, wherein the lanthanide chelate derivative has the formula M-L-Y (I), wherein Y is a lanthanide chelate; L is a linker and M is a polymerizable moiety.
The invention concerns also the novel lanthanide chelate derivative M-L-Y (I). Further, the invention concerns a novel particle comprising a lanthanide chelate covalently bound to an organic polymer or copolymer via a linker.
Europium(III) chelates based on β-diketone and thienylpyridine subunits tethered to an acrylamide function were synthesized. They were polymerised with styrene and acrylic acid in the presence or absence of trioctylphosphine. The photophysical properties of the nanobeads obtained are also discussed.
