Optical and nonlinear optical properties of new Schiff’s bases: experimental versus theoretical study of inclusion interactions

Three novel input logic gates supported by fluorescence studies: Organic nanoparticles (ONPs) as chemo-sensor for detection of Zn2+ and Al3+ in aqueous medium

“…), which is consistent with other studies [62][63][64]. For salenONPs, the fluorescence intensity was 8.5 F.U.…”

Mechanism of Nonlinear Optical Enhancement and Supramolecular Isomerism in 1D Polymeric Zn(II) and Cd(II) Sulfates with Pyridine-4-aldoxime Ligands

“…The pyridine-4-aldoxime was recently used as a component of the mixed crystal with efficient second harmonic generation NLO property . Since some of the crystals reported in this contribution belong to the centrosymmetric space groups, the second order nonlinearities vanish in crystals 1 , 3 , and 4 but can be observed in crystals 2 and 5 that belong to the acentric space groups ( P 2 1 and P 2 1 2 1 2 1 ).…”

Molecular design and physical properties of highly functionalized configurationally locked polyenes – an experimental and theoretical study

“…The synthesis of compounds with R 1 ¼ I-VII is according to the classical synthetic schemes reported by Schiff and Lemke. [48][49][50][51][52][53][54][55][56][57] The important specics are discussed for each of the subclasses. Equimolar amounts of isophorone (3,5,5-trimethyl-2-cyclohexene-1-one) (Sigma-Aldrich, purum >97.0%) and corresponding aromatic aldehydes are mixed in 50 mL toluene (or methanol) with stirring at r.t. for 6 h. To the reaction mixtures are added ˛2-10 mL concentrated CH 3 COOH and 3 drops piperidine or 5 mL of a 0.1 M solution of L-proline dissolved in water, which acts as a catalyst.…”

“…They are unfortunately characterized by complex synthetic behaviour, low yields and several competitive unwanted reactions, under the classical Lemke or Schiff schemes. [48][49][50][51][52][53][54][55][56][57] These derivatives however allowed isolation of 1D-3D crystals, in parallel thin lms and polymers, due to the polymerization of the nucleoside residues. Therefore further efforts towards the improvement of the synthetic reactions are justied for 47-50 and 71-73, respectively.…”

“…Thus: (i) the obtained derivatives primarily could be isolated as 1D-3D crystals and/or thin lms (Scheme 1); (ii) analogues with morpholine fragments at the R 2position oen underwent cleavage of the ring; and (iii) optimization of reaction conditions is necessary for compounds with S-containing analogues at the R 1 position, due to the redox processes that occur; (iv) the CLPs are obtained at 5-7 staging synthesis in ionic liquids. [48][49][50][51][52][53][54][55][56][57] It is of particular importance to note that the MS techniques involving the MALDI-MS method Journal of Materials Chemistry C Paper allowed direct crystalline phase analysis, in addition to the NLO and THz-characterization of thin and ultra-thin lm phases. On the other hand, the possibility for obtaining the protonated forms of the CLPs by the interaction with the polyfunctional acids as more preferred materials, particularly those used as matrices in the MALDI-MS imaging assay, provides a new direction for further studies.…”
