A novel emissive molecular system is constructed by the intercalation of the fluorophore melem (triamino-tri-s-triazine) within a Langmuir-Blodgett (LB) film of stearic acid with the periodic arrangement of lanthanides (Ln(III)), mainly Pr(III) with

The electronic and structural behaviour of a Pr(III) complex with 4,7-diphenyl-1,10-phenanthroline, [Pr(bathophen)(2)(NO(3))(3)], is investigated with respect to the effect of configuration changes on the Pr(III) centre. [Pr(bathophen)(2)(NO(3))(3)]

The intramolecular excitation energy transfer from the fluorophore ligand (phens) to Pr(III) in the complexes on the basis of the picosecond time-resolved luminescence spectra is discussed. These complexes exhibit sequentially multiplex emissions fro

Melamine or melem forms a coordination compound with Pr(III). From detailed measurements of electronic absorption and luminescence spectra reported here, it can be concluded that the excitation energy transfer of the Pr(III)–melamine complex occurs

When a chloroform solution of a dicyano(diimine)platinum(II) complex, [Pt(CN)2(5,5‘-dinonyl-2,2‘-bipyridine)], was spread onto pure water, a reversible surface pressure−molecular area curve was obtained. The surface pressure began to increase s

The [Pt(en)(L)]2+ (L = bipy or phen) complexes with a planar α-diimine ligand and a non-planar diamine ligand formed 1∶1 integrated stacks taking up free phen and phenanthrene (phe) selectively. The stacking structures of the composite crystals [P

The hexacyanoferrate(II) ion ([Fe(CN)6]4−) was rapidly oxidized to [Fe(CN)6]3− by a radical anion, I2−·, which was formed by a reaction between the copper(II) ion and the iodide ion. The oxidation reaction was accelerated by increasing the pH.
