Abstract: Reaction of ferrocenyl carboxylic acid with lanthanide salts gave di- and trimeric complexes bearing 6 and 9 organometallics. Square wave voltammetry and DFT studies showed that electrostatic repulsion determines the distribution of redox events.

Multicolor emissive Schiff base lanthanide Poly(methyl methylacrylate) [PMMA] composite films are fabricated for white light generation. Three isostructural lanthanides (III) complexes [EuIII2(L)2(NO3)2(dmf)2 (1), TbIII2(L)2(NO3)2(dmf)2 (2) and GdIII2(L)2(NO3)2(dmf)2 (3)] are synthesized, characterized from the ligand obtained by 1:1 condensation of salicylaldehyde and 2‐(2‐Aminoethoxy)ethanol, H2L. The photoluminescent studies revealed pure blue, green, and red color emissions from GdIIIL, TbIIIL, and EuIIIL complexes, although the central metal centers have identical dodecahedron geometry. Intensified ligand emission is attested for the blue emitter‐GdIIIL complex while the “antenna effect” is witnessed for green TbIIIL and red EuIIIL complexes. Co‐doping these multicolor luminescent emitters into the PMMA polymer the intensity of luminescence improved. A conscientious combination of red‐EuIIIL with green‐TbIIIL Lanthanide metal Schiff base complexes in a specified concentration, distinct white light is accomplished for the first time with Commission Internationale de I’Éclairage (CIE) values of 0.33, 0.30, very close to the ideal white emitter. The newly developed lanthanide‐Schiff base‐PMMA composite films are transparent and highly desired materials in optoelectronics, microscopy, and sensing.
