“…In this particular case, structural effects, such as structure distortion, or the number of rings have played an important role. On the other hand, photoluminescent properties of the newly synthesized Schiff base N-(4-dimethylaminophenyl)-3,5-di-tbutyl salicylaldimine have been investigated [24] and found to exhibit a significant response to Fe 3+ leading to a decrease in fluorescence intensity.…”

Copper(II) and cobalt(II) complexes of salicylaldimine obtained by the condensation of N,N-diethyl-2-methyl-1,4-phenylenediamine with 3,5-di-tert-butyl-2-hydroxybenzaldehyde have been synthesized and characterized by elemental analyses, magnetic susceptibility measurements, cyclic voltammetry, and FT-IR and UV-Vis spectroscopy. The molecular structure of the title copper(II) complex was determined by the single crystal X-ray diffraction technique. The Cu(II) center is coordinated by four atoms of the donor set in a compressed tetrahedral trans-[N 2 O 2 ] environment, which can be essentially ascribed to the presence of bulky fragments of the ligand. The computed bond valences of the copper verify +2 oxidation state and indicate that the copper bonds, in particular Cu-N bonds, are elongated due to steric effects from bulky substituents in the ligands, N-(4-diethylamino-2-methylphenyl). Intermolecular C-HÁÁÁp interactions leading to centrosymmetric synthons serve to stabilize periodic organization of the molecules.

“…Besides these known fl uorescent compounds, new materials are also being developed, such as Schiff-bases of salicylaldehyde with amine-substituted anthraquinones and benzophenones. 27,28 The second involves the determination of the color and fl uorescence characteristics of these candidate materials under corrosion conditions. The third involves the use of the candidate materials in a paint/ primer system to formulate smart coatings for detecting hidden corrosion on the metal substrate.…”

“…A number of fluorescent receptors have been designed and synthesized and they exhibit a pronounced selectivity for a particular metal ion. However, only a few have reported on fluorescent chemosenors for Fe 3 þ ion [14][15][16]. Oter et al [14] reported an optical Fe 3 þ ion sensor based on N-(4-dimethylaminophenyl)-3,5-di-t-butyl salicylaldimine, a Schiff base, as the fluorescence receptor, in which a cumbersome synthesis was involved and the sensor was dependent on pH condition.…”
