Description:
AbstractEuropium‐containing monomers with different bidentate and tridentate N‐donor ligands carrying norbornoyl side chains and theonyl trifluoroacetylacetonate (TTA) as coligand are obtained and incorporated in random copolymers and amphiphilic block copolymers using ring‐opening metathesis polymerization (ROMP). The characteristic bright red long‐lived europium luminescence is retained in the polymers. The polymers are characterized (using 1H NMR spectroscopy, gel permeation chromatography, differential scanning calorimetry, fluorescence spectroscopy, and dynamic light scattering) and tested as water vapor sensor materials. A sensitivity increase over time and changes in the luminescence spectra of the polymer samples indicate dissociation of Eu(TTA)3 from the polymer chains.
