✦ Synopsis

Aromatic carboxylates of the rare earths are known for highly efficient luminescence, thus holding the promise of applicability in optical devices, but may be problematic to apply as such due to their structure, which is polymeric in nature. Therefore, means of conversion into molecular species or eventually polymer embeddings are sought, while at the same time maintaining their advantageous optical features. For these purposes, co-ligations of rare earth p-aminobenzoates with bidentate bipyridine and phenanthroline, tridentate terpyridine and polyurethanes, which may also be perceived as polydentate ligands, have been carried out. The materials were characterised with focus on their structure [a
