The electronic absorption spectra of thymol have been recorded and studied in various solvents of different polarities. Multiple linear regression technique was applied to calculate the regression and correlation coefficients based on an equation that relates the wavenumbers of the absorption band maxima (νmax) to the empirical Kamlet–Taft solvent...

... values signify transition energy which also reflects the stabilization of the thymol in its ground state in a given solvent. From Table 4-A, maximum E T (Thymol) is in the case of diethyl ether and chloroform and from Table 4-B, maximum E T (Thymol) is in the case of acetic acid and THF. Therefore, E T (Thymol) provides a direct empirical measure of thymol solvation behavior. ...

... ε is the dielectric constant and n is the refractive index and both these quantities reflect the freedom of motion of electrons in the solvent and the dipole moment of the molecules. Empirical parameters of solvent polarity are given in Table 4. Figure 6A and 6B shows trend similar to that depicted in Figure 4A and 4B when the spectral positions (λmax) of the thymol were plotted against the solvent polarity parameter φ(ε, n), but the enhancement in this case is that more correlation observed. ...

Kraft lignin was catalytically graphitized to graphene-based nanostructures at high temperature under non-oxidative atmospheres. To obtain the best catalytic performance, a uniform catalyst–lignin mixture must be made by bonding transitional metal (M) ions to oxygen (O), sulfur (S) or nitrogen (N)-containing functional groups in kraft lignin. One o...

The lithium-sulfur (Li-S) battery is one of the promising energy storage alternatives because of its high theoretical capacity and energy density. Factors governing the stability of polysulfide intermediates in Li-S batteries are complex and are strongly affected by the solvent used. Herein, the polysulfide reduction and the bond cleavage reactions...

... It has become customary to multiply the vibrational frequencies by the scaling factor of 0.966 for 6-311G(d,p) basis set because the DFT method overestimates the vibration modes [25]. Time-dependent density functional theory (TD-DFT)/B3LYP based simulations have been fulfilled to provide UV-Vis spectrum in the excited state in six different solvation of water, methanol, ethanol, chloroform, dichloromethane, and dimethyl sulfoxide (DMSO) to understand the impact of solvation on the value of the absorption peaks of the title molecule [26,27]. The chemical shift of the title azo dye has been predicted by investigating the hydrogen and carbon nuclear magnetic resonance (NMR). ...

4-({4-[Bis(2-cyanoethyl)amino]phenyl}diazinyl)benzene sulfonamide is the azo dye material which has general application in the textile industry. Experimentally, it has been synthesized and geometrically characterized by G. Gervasio et al. In this study, the theoretical analysis has been calculated by using the ab-initio method based on the Density Functional Theory/B3LYP/6-311G(d,p) to characterize the structural, spectroscopy, and electronic properties of the title azo dye. Its molecular geometries are in good agreement with those of available experimental data. 129 vibrational modes have been specified with stretching, in-plane-bending, out-of-plane-bending, and torsion vibration modes by the Potential energy Distribution analysis. The ultraviolet spectra appear in a single peak for six common solvation at 429 nm. The Gauge-Invariant Atomic Orbital approach has been applied to predict the chemical shifts of 1H and 13C NMR only in DMSO solvation. The electronic properties have been investigated such as the energy bandgap (3.34 eV), ionization potential energy (6.24 eV), electron affinity (2.90 eV), electronegativity (4.57 eV), and chemical hardness (1.67 eV) by using the Frontier Molecular Orbital Theory from the energy interaction of the Lowest Unoccupied Molecular Orbital and Highest Occupied Molecular Orbital. The characterization of the title azo dye is conducted theoretically for the first time in this study.
... The solvent effects can be associated with specific (donor-acceptor and acidbase interactions) or non-specific (solvent acting as a dielectric continuum) interactions [51]. The Kamlet-Taft and Catalán empirical solvent scales were used to assess the interactions affecting the fluorescence emission (discussion provided in Supplementary Materials) [52][53][54][55][56]. Van der Waals and exciton interactions with the solvent are mainly associated with shifts in fluorescence emission in organic solvents, while changes observed in water are the result of the specific interactions [51]. ...

Self-assembled peptide-based hydrogels are promising materials for biomedical research owing to biocompatibility and similarity to the extracellular matrix, amenable synthesis and functionalization and structural tailoring of the rheological properties. Wider developments of self-assembled peptide-based hydrogels in biomedical research and clinical translation is hampered by limited commercial availability allied to prohibitive costs. In this work a focused library of Cbz-protected dehydrodipeptides Cbz-L-Xaa-Z-ΔPhe-OH (Xaa= Met, Phe, Tyr, Ala, Gly) was synthesised and evaluated as minimalist hydrogels. The Cbz-L-Met-Z-ΔPhe-OH and Cbz-L-Phe-Z-ΔPhe-OH hydrogelators were comprehensively evaluated regarding molecular aggregation and self-assembly, gelation, biocompatibility and as drug carriers for delivery of the natural compound curcumin and the clinically important antitumor drug doxorubicin. Drug release profiles and FRET studies of drug transport into small unilamellar vesicles (as biomembrane models) demonstrated that the Cbz-protected dehydropeptide hydrogels are effective nanocarriers for drug delivery. The expedite and scalable synthesis (in 3 steps), using commercially available reagents and amenable reaction conditions, makes Cbz-protected dehydrodipeptide hydrogels, widely available at affordable cost to the research community.

Oxindoles and their derivatives have become an important compound on account of promising applications in medicine. Chlorine is found in azole group compounds used for fungal infections and is used in cancer chemotherapy drugs. In this study, the optimized molecular geometry, natural bond orbital (NBO) analysis, non-linear optical (NLO) properties and vibrational frequencies of chlorine-containing oxindole (6-chloro-2-oxindole) in monomer and dimer forms have been investigated using DFT/B3LYP/6-311++G(d,p) method. The Hirshfeld surface and fingerprint analyses have been used to examine intermolecular interactions of the 6-chloro-2-oxindole compound. The reduced density gradient (RDG) analysis has been employed to investigate hydrogen bonding, Van der Waals interactions and the steric effect in the rings. The electronic properties and transitions for UV-Vis analysis have been calculated using the TD-DFT/B3LYP/6-311++G(d,p) method in monomeric and dimeric forms. The experimental spectral analysis of 6-chloro-2-oxindole has been investigated using UV-Vis, FT-IR and FT-Raman spectra. The antitumor activities of 6-chloro-2-oxindole with different receptors (3VNT, 3VHE and 5VZ2) have been performed by molecular docking analysis. Molecular docking calculations show the inhibitor effect against tyrosine kinase receptors.
