A pre-formed catalyst Pd2+/PANI composite for C-C coupling reaction was synthesized by combining the self-stabilized dispersion polymerization method with the in-situ composite material. Experiments have confirmed that the relatively high reduced structure (75%) in the polyaniline carrier is more favorable for the coupling reaction. Raman spectroscopy, solid nuclear magnetic, and X-ray photoelectron spectroscopy were performed to characterize the structures. The pre-formed catalyst has uniform coordination of divalent palladium and nitrogen in different valence states of the carrier polyaniline, which shows a good synergistic effect in the catalytic Ullmann reaction, and greatly reduces the use of reducing agents such as hydrazine hydrate. Compared with other studies, we analyzed the catalytic reaction mechanism in detail through real-time online infrared and XPS characterization. The results show that the divalent palladium in the catalyst and the zero-valent palladium generated by the in-situ reaction synergistically promote the reaction, while the polyaniline support acts as a stabilizer and dispersant, which prevents the agglomeration of the metal particles and prolongs increased catalyst life. The prepared Pd2+/PANI composites will become the most attractive alternative to traditional organic materials due to their wide applicability, high catalytic activity, stable recycling and relatively low price. This work provides a new theoretical basis for the understanding of the essential driving force of PANI catalytic activity and the cognition of the micro mechanism of action. (C) 2020 Elsevier Inc.

Typically, Suzuki couplings used in polymerizations are performed at raised temperatures in inert atmospheres. As a result, the synthesis of aromatic materials that utilize this chemistry often demands expensive and specialized equipment on an industrial scale. Herein, we describe a bimetallic methodology that exploits the distinct reactivities of palladium and copper to perform high yielding aryl-aryl dimerizations and polymerizations that can be performed on a benchtop under ambient conditions. These couplings are facile and can be performed by simple mixing in the open vessel. To demonstrate the utility of this method in the context of polymer synthesis: polyfluorene, polycarbazole, polysilafluorene, and poly(6,12-dihydrodithienoindacenodithiophene) were created at ambient temperature and open to air.

Two novel triphenylamine-based derivatives with dimethylamino substituents, N,N’-bis(4-dimethylaminophenyl)-N,N’-bis(4-methoxyphenyl)-1,4-phenylenediamine (NTPPA) and N,N’-bis (4-dimethylaminophenyl)-N,N’-bis ( 4-methoxypheny1)-1,1′-biphenyl-4,4′-diamine (NTPB), were readily prepared for investigating the optical and electrochromic behaviors. These two obtained materials were introduced into electrochromic devices accompanied with heptyl viologen (HV), and the devices demonstrate a high average coloration efficiency of 287 cm(2)/C and electrochemical stability. Besides, NTPB/HV was further used to fabricate electrofluorochromic devices with a gel type electrolyte, and exhibit a controllable and high photoluminescence contrast ratio (I-off/I-on) of 32.12 from strong emission to truly dark by tuning the applied potential in addition to a short switching time of 4.9 s and high reversibility of 99% after 500 cycles.

The purpose of this work is to prepare effective adsorbents for simultaneously removing Hg(ii) ion and aromatic pollutants in water, which still remains a great challenge presently due to their different physicochemical properties. Herein, two new thiol-/thioether-functionalized porous organic polymers were prepared and characterized by scanning electron microscopy, infrared spectra, C-13 CP/MAS nuclear magnetic resonance spectra, energy-dispersive X-ray spectroscopy, elemental analysis, thermo-gravimetric analysis, and nitrogen adsorption-desorption isotherms. The results showed that the two adsorbents had a loosely porous structure, high BET surface area, and good thermal and chemical stability. The optimal pH value for the two new adsorbents to uptake Hg(ii) was 3-4. The new adsorbents presented a high adsorption ability with the maximum adsorption capacity of 180 mg g(-1) for Hg(ii) and 358-452 mg g(-1) for aromatic pollutants (toluene and m-xylene as models) and acceptable/fast binding kinetics for Hg(ii) and aromatic pollutants, respectively. The adsorbents also showed high adsorption selectivity for Hg(ii) in the presence of commonly coexisting metal ions. Moreover, the two adsorbents had good simultaneous removal ability for Hg(ii) and the aromatic pollutants at different concentrations and good reusability. Finally, the two new adsorbents were used successfully for the simultaneous and highly efficient removal of Hg(ii) ion and aromatic pollutants in simulated sewage with removal efficiencies higher than 88% for Hg(ii) and higher than 93% for the aromatic pollutants (10 mg of adsorbent mixed with 10 mL of sewage containing Hg(ii) and the aromatic pollutants at 10 g mL(-1) for each one), indicating their great potential to be applied for the simultaneous removal of Hg(ii) and aromatic pollutants in real sewage or wastewater.

The present work demonstrates the operation of a reversible supramolecular gate, i.e., an ensemble of various components linked by chemical communication, which is triggered by stoichiometric chemical inputs and by obeying the AND truth table delivers a stoichiometric chemical signal. The output triggers a series of events that finally set up a catalytic process. In detail, a three-component AND gate, composed of two distinct nanoswitches, a copper-loaded and an unloaded one {= state (0,0)}, was actuated with stoichiometric amounts of two inputs (IN-1 = Zn2+, IN-2 = Hg2+) generating copper(I) ions as output in state (1,1). The utility of this information processing was highlighted by using the copper(I) output for triggering the self-assembly of the four-component rotor ROT-2 through metal translocation. In the presence of suitable reactants, ROT-2 acted as a catalytic machinery catalyzing a click reaction (= signal amplification). Verification of the functioning of the AND gate in a mixture of 12 components was thus accomplished by monitoring formation of the click product. Due to the stoichiometric design, the gate was reset to state (0,0) by adding hexacyclen and reactivated by adding inputs IN-1 and IN-2 alike in the first cycle.

A modular synthesis of multi-functionalized biphenyl, terphenyl and higher linear oligophenylene dicarboxylic acids and pyridine-terminated oligoarenes by stepwise palladium-catalyzed borylation/Suzuki-Miyaura cross-coupling reactions is described. The presence of several distinct functional groups such as azide, hydroxy, and alkyne, as well as coordinative functional end groups (carboxylic acid or pyridine) combined in a single oligoarene molecular unit at strategic positions offer an advantageous dual-utility. First, these compounds can serve as useful molecular bricks (ditopic organic linkers) in the construction of complex porous crystalline materials. Second, after the assembly into the crystalline coordination networks, orthogonal functional sites within the linker-backbone offer tremendous potential from application perspectives as they can be modified by a wide range of post-synthetic modifications including azide-alkyne click chemistry. This allows further tailoring of the supramolecular assemblies to yield novel multifunctional materials.

Novel magnetic CoFe2O4-embedded MIL-101(Cr) with tetramethylammonium hydroxide (CoFe2O4/MIL-101T) was prepared through the facile hydrothermal method. Tetramethylammonium hydroxide acts as a template molecule and avoids the recrystallisation of terephthalic acid. The material was applied as the adsorbent in the magnetic solid-phase extraction (MSPE) process coupled with high-performance liquid chromatography to detect the five flame retardants in environmental water samples. Several parameters affecting MSPE efficiency were systematically investigated, such as MIL-101T content, material amount, desorption solvents, adsorption time, solution pH, theoretical maximum enrichment factor (EFmax) and the reusability. Under optimised conditions, good linearities were achieved for five flame retardants with correlation coefficients R-2 > 0.9961. The limits of detections for analytes at the signal-to-noise ratio of three were 0.013-0.071 mu g center dot L-1. This method was applied to the analysis of tap, pond, lake and river waters. The recoveries were in the range of 81.5 +/- 3.2-107.0 +/- 2.3% with the relative standard deviations ranging from 0.11% to 8.66% in four real water samples. The adsorption mechanism was the hydrophobic interaction between the material and the analytes besides pore adsorption action of the material.
