Rezumat

A series of lanthanide coordination compounds LnL3, LnL3Phen, and LnL3Dipy with aryl-functionalised carbacylamidophosphate (CAPh) ligand N-(diphenylphosphoryl)benzamide (HL= PhC(O)N(H)P(O)Ph2) were synthesized for luminescent thin films producing. The bulky organic ligands provide a hydrophobic shell around Lniii ion leading to highly luminescent terbium and europium complexes with long-lived emission. The thin films of the complexes were obtained by spin coating and, for the first time, by vacuum evaporation. The films exhibit an intensive monochromatic photoemission with decay times equal to 0.78-1.34 ms
