Since the discovery of the living free-radical polymerization, alkoxyamines were widely used in nitroxide-mediated polymerization (NMP). Most of the known alkoxyamines bear just one functionality with only a few exceptions bearing two or more alkoxyamine units. Herein, we present a library of novel multidimensional alkoxyamines based on commercially available, rigid, aromatic core structures. A versatile approach allows the introduction of different sidechains which have an impact on the steric hindrance and dissociation behavior of the alkoxyamines. The reaction to the alkoxyamines was optimized by implementing a mild and reliable procedure to give all target compounds in high yields. Utilization of biphenyl, p-terphenyl, 1,3,5-triphenylbenzene, tetraphenylethylene, and tetraphenyl-methane results in linear, trigonal, square planar, and tetrahedral shaped alkoxyamines. These building blocks are useful initiators for multifold NMP leading to star-shaped polymers or as a linker for the nitroxide exchange reaction (NER), to obtain dynamic frameworks with a tunable crosslinking degree and self-healing abilities.

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.

Selective and large-scale synthesis of [8]-cycloparaphenylene (CPP) was achieved in seven steps starting from commercially available 4-bromo-4′-hydroxybiphenyl and 4,4’dibromobiphenyl. The key unsymmetrical tetraring unit, 4-bromophenyl and 4′-bromobiphenyl-substituted cis-1,4-bis(triethylsiloxy)-2,5-cyclohexadiene-1,4-diyl (5fA), was synthesized on an similar to 50 g scale by stereoselective cis-addition of 4-bromo-4′-lithiobiphenyl to 4-(4-bromophenyl)-4-hydroxy-2,5-cyclohexadienl-one, which was synthesized on an similar to 100 g scale. Platinum-mediated selective dimerization of the four-ring unit 5fB and subsequent reductive aromatization of the cyclohexadiene-diyl by H2SnCl4 gave 2 g of [8]CPP in 6.6% overall yield (10.2% on small scale).

Two branched oligophenylenethynylenes with phenylene or biphenylene moieties as inter-nodal fragments are synthesized by the Sonogashira reaction for optoelectronic applications. The branching of polyphenylenethynylenes influences the electro-optical properties, but cannot be precisely controlled, while its determination is often hardly addressed. The optical investigation, supported by nuclear magnetic resonance (NMR) studies, of oligophenylenethynylenes and the properly synthesized model compounds is performed to get insights on the branching and related effect on the material performance. The proposed branched oligophenylenethynylenes are good ultraviolet emitters in solution, while in solid-state aggregation phenomena strongly affect emission properties. However, the interactions between pi-electrons on phenylene and ethynylene of neighboring molecules in films enhance intermolecular charge transport (hole mobility = 3.2 x 10(-3) cm(2) V(-1)s(-1)) making them optimal candidates as hole transport materials in optoelectronic devices. The insertion of the oligophenylenethynylene film as a hole transporting layer in multilayered solution processes blue, green, and red electroluminescent diodes, enhances OLEDs electro-optical properties.

Herein, we report a Ni-catalyzed reductive coupling for the synthesis of benzonitriles from aryl (pseudo)halides and an electrophilic cyanating reagent, 2-methyl-2-phenyl malononitrile (MPMN). MPMN is a bench-stable, carbon-bound electrophilic CN reagent that does not release cyanide under the reaction conditions. A variety of medicinally relevant benzonitriles can be made in good yields. Addition of NaBr to the reaction mixture allows for the use of more challenging aryl electrophiles such as aryl chlorides, tosylates, and triflates. Mechanistic investigations suggest that NaBr plays a role in facilitating oxidative addition with these substrates.
