Polyamides with phosphaphenanthrene skeleton and substituted triphenylamine for gas separation membranes

Molecular dynamics (MD) and Monte Carlo (MC) simulations were used to study the structural and gas transport properties of a group of three highly permeable glassy polyamides containing phosphaphenanthrene skeleton and substituted triphenylamine side groups. The polymer chains were relaxed using a combination of canonical and isothermal-isobaric ensemble simulations to obtain the final equilibrium density. The grand canonical Monte Carlo method coupled with a canonical MD simulation was used to study the solubility of small gases in these polymers. The accuracy of the methods used in this work was tested and validated by comparing the physical and gas transport properties of gases with the available experimental data. The presence of large bulky side groups along the rigid backbone of the polymer, hinders its efficient packing and results in a superior free volume distribution. The computed diffusivities and solubilities of gases are significantly higher for the poly-amides containing both phosphaphenanthrene and trityl-substituted triphenylamine side groups. The thermal motion of the gases, which results in frequent jumps from one free volume region to another, is enhanced with the availability of larger cavities. These molecular details can provide critical information for the experimental design of highly selective and efficient gas separation membranes.

A Supramolecular Nanocomposite as a Near-Infrared-Transmitting Optical Filter for Security and Forensic Applications

Visibly opaque but near-infrared (NIR)-transparent materials are an essential component for night-vision photography, security imaging, and forensic applications. Herein, the development of a novel supramolecular black dye from a diketopyrrolopyrrole (DPP)-based low-molecular-weight organogelator is described. In the solution state, the monomer of DPP-Amide exhibits a deep green color with a broad absorption in the visible region due to firm intramolecular charge transfer from the donor to the acceptor unit. Interestingly, due to the synergistic effect of H-bonding and p-stacking, DPP-Amide can form a black organogel in toluene with complete spectral coverage from 300 to 800 nm, and transmits beyond 850 nm. In the gel state, complete visible-spectrum coverage is achieved due to the simultaneous formation of both H-and J-type aggregates, which is confirmed via absorption studies. To create a free-standing NIR-transmitting elastomeric black filter, nanoscopic molecular aggregates of DPP-Amide (0.15 wt%) are embedded into a poly(dimethylsiloxane) matrix. This nanocomposite possesses high NIR transparency with good thermal and photostability for practical applications. Finally, the use of the developed material for NIR photography, security, and forensic-related applications is demonstrated.

Multigram-scale flow synthesis of the chiral key intermediate of (-)-paroxetine enabled by solvent-free heterogeneous organocatalysis

The catalytic enantioselective synthesis of the chiral key intermediate of the antidepressant (-)-paroxetine is demonstrated as a continuous flow process on multi-gram scale. The critical step is a solvent-free organocatalytic conjugate addition followed by a telescoped reductive amination-lactamization-amide/ester reduction sequence. Due to the efficient heterogeneous catalysts and the solvent-free or highly concentrated conditions applied, the flow method offers key advances in terms of productivity and sustainability compared to earlier batch approaches.

The impact of gamma-irradiation from radioactive liquid wastewater on polymeric structures of nanofiltration (NF) membranes

In this study, the impacts of gamma-irradiation from the lowand intermediate-level liquid radioactive wastewaters (LILW) to polyamide (PA) structures of nanofiltration (NF) membranes were investigated. As the gamma irradiation increased to 300 kGy in the aqueous solution at 5 bar, both the salt rejection and the water permeability of NF membranes were decreased from 95.6 +/- 0.1%-74.6 +/- 0.5%, and from 33.7 +/- 0.3 LMH to 21.4 +/- 0.5 LMH, respectively. The surface free energy and Young’s modulus of the membrane indicated the decrease in hydrophilicity and the increase in fragility of PA structure after gamma-irradiation. X-ray photoelectron spectroscopy and the streaming potential analysis exhibited that the gamma-irradiation resulted the increase in the cross-linked portion of the amide bonding from 28% to 45% due to the gamma-induced new bonding between unbound carboxylic groups and amine groups. Nuclear magnetic resonance analysis confirmed that the poly(pphenylene) in polyamide structure were changed to poly(cyclohexane) and poly(cyclohexene) by hydrogen radical disproportionation generated from the gamma-irradiated water, and it is responsible to the increase of the cross-linked PA structures. The decrease in salt rejection and water permeability is attributed to the aging of PA structures by gamma-irradiation, thus, should be carefully monitored during the treatment of LILW using NF membrane processes.

Structure and dynamics of cyclic amides: The rotational spectrum of 1,3-dimethyl-2-imidazolidinone

The structure and the internal dynamics of the lactam 1,3-dimethyl-2-imidazolidinone, also known as N, N’-dimethylethyleneurea, have been investigated through the analysis of its free jet absorption rotational spectrum. One conformer has been assigned. The pure mu(b)-type spectrum, recorded in the 59.6-74.4 GHz frequency range entails an inertial defect Delta(c) = -16.39 u angstrom(2), indicating that the molecule has C-2 symmetry with a twisted arrangement of the ring. The methyl internal rotation barrier V-3 = 7.181 (3) kJ mol(-1) and the N-14 diagonal nuclear quadrupole coupling constants x(aa)= 2.14 (14) and (X-bb-X-cc) = 7.26 (6) MHz were determined from the analysis of the hyperfine structure.

Prolonged bioluminescence imaging in living cells and mice using novel pro-substrates for Renilla luciferase

The prodrug or caged-luciferin strategy affords an excellent platform for persistent bioluminescence imaging. In the current work, we designed and synthesized ten novel pro-substrates for Renilla luciferase by introducing ester protecting groups of different sizes into the carbonyl group of the free luciferin 1. Taking advantage of intracellular esterases, lipases, and nucleophilic substances, the ester protecting groups were hydrolyzed, resulting in the release of a free luciferin and a bioluminescence signal turn-on. Among the tested pro-substrates, the butyryloxymethyl luciferin 7 exhibited low cytotoxicity and a prolonged luminescence signal both in cellulo and in vivo. Therefore, the butyryloxymethyl luciferin 7 can act as a promising substrate for noninvasive extended imaging in diagnostic and therapeutic fields.

In silico studies on CNR1 receptor and effective cyanobacterial drugs: Homology modelling, molecular docking and molecular dynamic simulations

Cannabinoid receptor 1(CNR1) is strongly related with A G-protein coupled receptors that have been found to exist in the organ systems of human beings. It has an important role to play as therapeutic targets in certain challenging diseases globally (cancer, diabetes, obesity, cardiac dysfunction, CNS disorders, inflammation and pain). This computational study was carried out in Schrodinger suite packages like prime application, sitemap generation, grid and glide SP that are available in version 10.2 Maestro. The target CNR1 was retrieved from UniProt, and cyanobacterial bioactive compounds (ligands) were obtained from chemical database. Homology modelling acts as an effective tool for docking studies in these proteins. As a result, homology modelled target exhibited low sequence similarity and thus the molecule was made as the quality target. The bioactive molecules such as Symplocamide A, Pompanopeptine B, Lyngbyastatin 5, Lyngbyabellin D, Hoiamide A, Nostocylopeptide A3, Lyngbyabellin H, and Cryptophycin 327 are chosen from various cyanobacterial species based on their biological and pharmacological activities. Among the eight cyanobacterial molecules, Symplocamide A had a potent docking score and revealed good binding affinities than other ligands. According to the results we suggest that Symplocamide A could be developed as a potential drug molecule for CNR1 targets.

A novel composite based on pyrene thiazole grafted on graphene oxide: physico-chemical characterization and electrochemical investigations

We report the obtaining of a new composite starting from pyrene thiazole, a compound certified by nuclear magnetic resonance and its covalent grafting on the surface of graphene oxide. Novel material was synthesized in two stages: the first involving transformation of carboxyl groups of graphene oxide into acid chlorides and the second the amide reaction between acid chloride and amine group of pyrene thiazole (PTC). Numerous characterization methods have been used to certify this material, such as: Raman spectroscopy, fluorescence, infrared spectroscopy and X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. Their results show the successful covalent functionalization of graphene oxide with pyrene thiazole through the formation of amide bonds. The electrochemical investigation consisted of evaluating the redox behavior of the carbon screen printed electrodes modified with the new composite (GO-PTC) using caffeic acid, as analyte. From analytical point of view, it is relevant to be able to quantify the presence of caffeic acid and for such reason we used as analytical method the square wave voltammetry. The results showed that the GO-PTC modified carbon screen printed electrodes were able to detect the caffeic acid over more than one order of magnitude (linear working range: 0.005-0.1 mM) and GO-PTC modified electrodes can be considered promising for other analytical investigations.
