Traditionally, electrochromic materials rely on counter redox materials like ferrocene to realize redox processes. In this work, two novel, closely related series of electrochromic materials bearing push-pull electronic structure were designed and synthesised (N,N,N’,N’-tetra(pyridin-4-yl)-1,4-phenylenediamine derivatives (TPPDs) and N,N,N ‘,N ‘-tetra(pyridin-4-yl)benzidine derivatives (TPBDs)). When stimulated by an external electric field, both series of compounds exhibited intramolecular charge transfer because of their push-pull electronic structures. Therefore, the TPPDs and TPBDs could undergo redox processes without the assistance of counter electrode chemicals. Furthermore, the TPPDs and TPBDs could replace the electrolyte that is required in conventional electrochromic devices (ECDs) because of their conductivity. This allowed the fabrication of a simple, single-component ECD.

The development of novel multi-substituted aryl-phosphonate compounds offers promise as new building blocks for metal-organic frameworks (MOFs) materials with excellent properties in regards to porosity and gas sorption. We demonstrate the efficiency of the palladium-catalyzed Hirao cross-coupling reaction in the synthesis of substituted phosphonates; however, attempts to prepare derivatives with isoretical expansion through the cyclization of 4-(4?-bromophenyl)acetophenone resulted in an extremely low yield, with the isolation of the dimer intermediate. Ab initio calculations showed that while the trimerization of acetophenone is exothermic, that of 4-phenyl acetophenone is endothermic. By contrast, the cyclization of 4-(4?-bromophenyl)benzonitrile is exothermic and allows for the formation of the appropriate phosphonic acid. The benzonitrile methodology also allows for the formation of ortho methyl derivatives with high steric hindrance. All the multi-substituted aryl-phosphonate compounds reported herein can be prepared on a multi gram scale enabling researchers a wider range of building blocks for phosphonate MOFs.

The first unsubstituted olefin-linked covalent organic framework, termed COF-701, was made by linking 2,4,6-trimethyl-1,3,5-triazine (TMT) and 4,4′-biphenyldicarbaldehyde (BPDA) through Aldol condensation. Formation of the unsubstituted olefin (-CH=CH) linkage upon reticulation is confirmed by Fourier transform infrared (FT-IR) spectroscopy and solid-state C-13 cross-polarization magic angle spinning (CP-MAS) NMR spectroscopy of the framework and of its C-13-isotope-labeled analogue. COF-701 is found to be porous (1715 m(2) g(-1)) and to retain its composition and crystallinity under both strongly acidic and basic conditions. The high chemical robustness is attributed to the unsubstituted olefin linkages. Immobilization of the strong Lewis acid BF3 center dot OEt2 in the pores of the structure yields BF3 subset of COF-701. In the material, the catalytic activity of the guest is retained, as evidenced in a benchmark Diels-Alder reaction.

Cross-linked triarylamine-siloxane hybrid thin film have been formed using Piers-Rubinsztajn chemistry. Key to this approach was the use of a ring-opening reaction to prevent the evolution of volatile small molecules. A representative cyclic ether containing biphenyl triarylamine compound was synthesized and on ring-opening was shown to form a smooth, glassy, and electroactive films by cross-linking with tetrakis(dimethylsiloxy) silane (QM*4). It was found that the films were electrochemically active with low glass transition temperatures. Cross-linked films were incorporated into organic light emitting diodes (OLEDs) under various conditions and functionality within OLEDs was confirmed. Finally, the resistance of the system to dissolution (orthogonality) was considered by casting F8T2, a p-type emitting polymer, from solution on top of the cross-linked film, which formed a working OLED.

Organic pi-conjugated polymers (CPs) have been intensively explored for a variety of critical photocatalytic applications in the past few years. Nevertheless, CPs for efficient CO2 photoreduction have been rarely reported, which is mainly due to the lack of suitable polymers with sufficient solar light harvesting ability, appropriate energy level alignment and good activity and selectivity in multi-electron-transfer photoreduction of CO2 reaction. We report here the rational design and synthesis of two novel triphenylamine (TPA) based conjugated microporous polymers (CMPs), which can efficiently catalyze the reduction of CO2 to CO using water vapor as an electron donor under ambient conditions without adding any co-catalyst. Nearly 100% selectivity and a high CO production rate of 37.15 mu mol h(-1) g(-1) are obtained for OXD-TPA, which is significantly better than that for BP-TPA (0.9 mu mol h(-1) g(-1)) as a result of co-monomer change from biphenyl to 2,5-diphenyl-1,3,4-oxadiazole. This difference could be mainly ascribed to the synergistic effect of a decreased optical band gap, improved interface charge transfer and increased CO2 uptake for OXD-TPA. This contribution is expected to spur further interest in the rational design of porous conjugated polymers for CO2 photoreduction.

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.

A series of Pd/Fe2O3 nanohybrids with low metal content supported with Amberlite resin formate (Pd/Fe2O3@ARF) was prepared and characterized by FTIR, XRD, XPS, EELS, SEM-EDAX, and HRTEM. The coexistence of mainly crystalline Pd and Fe2O3 nanoparticles (NPs) of average size similar to 4-5 nm in the resin matrix was confirmed. These nanohybrids were used for hydrodehalogenation of polyhaloar-omatics using NaBH4 as a reducing agent in water. Notably, the composite Pd/Fe2O3@ARF-110 exhibits excellent catalytic performance in the hydrodehalogenation of different haloar-omatics. High TOF (in comparison to other related heterogeneous catalysts), recydability, and chemoselectivity between halide and C = C bond make this nanohybrid catalyst very attractive for the degradation of persistent organic pollutants originated from industries. The experimental observations and other analytical studies suggest that the enhanced catalytic activity could be due to strong interactions between Fe2O3 and Pd NPs that facilitate the cleavage of B-H bond and subsequent hydride generation.

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 benzyne-enabled desulfurization reactions have been demonstrated which convert diaryl sulfoxides and heteroaryl sulfoxides to biaryls and desulfurized heteroarenes, respectively. The reaction accessing biaryls tolerates a variety of functional groups, such as halides, pseudohalides, and carbonyls. Mechanistic studies reveal that both reactions proceed via a common assembly process but divergent disassemblies of the generated tetraaryl(heteroaryl) sulfuranes.
