“…Presently, TMs materials are very interesting in the study of nonlinear optical properties (NLO), especially that they have caught the attention of many specialists in the field of novel technology developments in optics and photonics [60–65] TMs materials can be used as amplifiers, [66,67] and they are attractive in many optical applications as all‐optical switching, [5,6,68,69] optical limiting [70,71] and also as optical devices [9–11] . Nonlinear optical phenomena may be produced by applying electromagnetic fields in various material systems in order to get new electromagnetic fields altered in amplitude, phase, frequency and other physical properties [11,72] .…”

“…Table exhibits the different NLO parameters as total static dipole moment (μ), the mean first‐order hyperpolarizability (β), the depolarization ratio (DR), the sum of the four hydrogen bonds lengths between the anion and the four N−H bonds of TUD1, and the Hyper‐Rayleigh scattering (β HRS ) for the studied complexes. The polarizabilities and first‐order hyperpolarizabilities were converted into electrostatic units (esu) using 8.6393×10 −33 esu for β as conversion factor and compared to those of NLO standard prototype . The analysis of the β parameters shows that all the studied complexes are an effective species for NLO materials, especially TUD1‐perchlorate, TUD1‐benzoate and TUD1‐salicylate complexes.…”

Thiourea derivative‐based carbon paste electrode (TUD1‐CPE) was constructed as a potentiometric sensor for the determination of salicylate anion in pharmaceutical formulations, Aspocid® and Aspirin®. The optimized CPE contained 45.5 % graphite, 0.5 % reduced graphene oxide (rGO), 46.0 % nitrophenyl octyl ether (NPOE) plasticizer, 5.0 % TUD1 ionophore, and 3.0 % tridodecylmethyl ammonium chloride as additive. The incorporation of NPOE of high dielectric constant, and rGO in electrode caused better performance of the sensor; Nernstian response of 59.0 mV decade−1 in the concentration range of 10−1–10−5 mole L−1, a detection limit of 1×10−5 mole L−1 in a very short response time of 6 seconds. The prepared sensor showed high selectivity against similar anions (i. e. ClO4- , benzoate, I−, SCN−). Selectivity was confirmed by calculating the formation constant (Kβ) using sandwich membrane method, where Kβ for TUD1‐salicylate is 100.43. Theoretical calculations at DFT‐B3LY/6‐31G** level of theory were performed to find interaction mechanism, Energies of HOMO and LUMO orbitals, non‐linear optical (NLO) properties (the electronic dipole moment (μ), first‐order hyperpolarizability (β), the hyper‐Rayleigh scattering (βHRS) and the depolarization ratio (DR)), and other global properties; these calculations showed lower values of β and DR, higher value of βHRS, and the shortest lengths of the four N−H bonds between TUD1 and salicylate which confirm their strong complexation and salicylate‐selectivity. Also, all the studied anion‐TUD1 exhibited relatively high NLO properties, and these results were considered as a preliminary study for investigating new types of NLO bearing materials. The sensors were applied successfully for the determination of salicylate anion in Aspocid® and Aspirin®.

“…On complexation, the FT‐IR spectra of the complexes exhibited ligand bands with the appropriate shifts due to complex formation. The band due to azomethine stretching appeared in the range 1675–1683 cm −1 , suggesting the involvement of azomethine group in coordination . In addition, the carbonyl region in the FT‐IR spectrum can be very distinctive and useful in assigning structures.…”

The interaction of Ru3(CO)12 with a novel family of monodentate V‐shaped Schiff base ligands (L1–4; L1: (E)‐1‐(4‐((4‐bromobenzylidene)amino)phenyl)ethanone, L2: (E)‐1‐(3‐(4‐(dimethylamino)benzylideneamino)phenyl)ethanone, L3: (E)‐1‐(4‐(4‐(dimethylamino)benzylideneamino)phenyl)ethanone, L4: (E)‐1‐(3‐(3,4‐dimethoxybenzylideneamino)phenyl)ethanone) in air under atmospheric pressure afforded the novel complexes [Ru(CO)3(L1–4)2]. The parent ligands and their complexes were characterized using elemental analyses and spectroscopic techniques. In addition, the structure of the representative ligand L1 was determined using single‐crystal X‐ray analysis. The stereochemistry and theoretical optimization of the three‐dimensional geometry of the ligands and their complexes were justified. In vitro antimicrobial screening against bacterial stains Escherichia coli and Staphylococcus aureus and fungus Candida albicans was conducted. Cytotoxicity of the compounds as anti‐tumour agents was evaluated against liver carcinoma (HepG2), breast carcinoma (MCF7) and colon carcinoma (HCT‐116) cell lines relative to cisplatin and doxorubicin. The complexes showed variable in vitro cytotoxic activities against the three studied cell lines, with IC50 values less than those of cis‐platin, and thus appear to be building blocks for promising anti‐tumour agents.
