Molecular Design of Highly Luminescent Lanthanide Complex with Heterocyclic Diimines

In order to obtain new highly luminescent materials two families of lanthanide complexes on basis of chlorides and carboxylates with heterocyclic diimines upon the different stoichiometric ratio for the latter were synthesized. A method for obtaining the partially anhydrous lanthanide chlorides, which not contain any OH oscillators in the first coordination sphere of the lanthanide ion, was elaborated. This gives a possibility to increase the luminescence intensity in 4.5 times.
