<i>In Situ</i> Luminescence of Self-Assembled Eu(III)-Naphthoic Acid Complex in Langmuir and LB Films.

ABSTRACT: Highly luminescent nanostructured films with controlled molecular organization may find applications in various areas, ranging from new drug delivery systems to solid-state lighting. In this work, we synthesized and characterized amphiphilic complexes [Ln(dion)₃(H₂O)(DMSO)] where Ln(III) = Eu or Gd and dion is 6-dodecyloxy-2-naphthoic acid. The ligand dion was prepared in high yield through a sequence of esterification, alkylation, and hydrolysis reactions, and its structure was confirmed by ¹H NMR analysis. The synthesis of the complexes was confirmed by CHN elemental analysis and FT-IR spectral data. The triplet level (T = 26,332 cm^-1) obtained from an isostructural Gd(III) complex confirms that the dion ligand acts as an antenna in the
