The realization of organic thin film transistors (OTFTs) with performances that support low-cost and large-area fabrication remains an important and challenging topic of investigation. The unique electrical properties of single-walled carbon nanotubes (SWNTs) make them promising building blocks for next generation electronic devices. Significant advances in the enrichment of semiconducting SWNTs, particularly via pi-conjugated polymers for purification and dispersal, have allowed the preparation of high-performance OTFTs on a small scale. The intimate interaction of the conjugated polymer with both SWNTs and the dielectric necessitates the investigation of a variety of conjugated polymer derivatives for device optimization. Here, the preparation of polymer-SWNT composites containing carbazole moieties, a monomer unit that has remained relatively overlooked for the dispersal of large-diameter semiconducting SWNTs, is reported. This polymer selectively discriminates semiconducting SWNTs using a facile procedure. OTFTs prepared from these supramolecular complexes are ambipolar, and possess superior mobilities and on/off ratios compared to homo poly(fluorene) dispersions, with hole mobilities from random-network devices reaching 21 cm(2) V-1 s(-1). Atomic force microscopy measurements suggest the poly(carbazole)-SWNT composites form more uniform thin films compared to the poly(fluorene) dispersion. Additionally, treating the silicon dioxide dielectric with octyltrichlorosilane is a simple and effective way to reduce operational hysteresis in SWNT OTFTs.

A nickel-catalyzed cross-electrophile coupling reaction between (hetero)aryl bromides and 2,2-difluorovinyl tosylate is presented. This protocol provides facile incorporation of the gem-difluorovinyl moiety in organic molecules. The method features mild reaction conditions, good functional group tolerance, and excellent yields. Furthermore, mechanistic experiments and DFT studies indicate a Ni(0)/Ni(II) catalytic cycle, thus differing from the currently accepted catalytic cycle for nickel-catalyzed C(sp(2))-C(sp(2)) cross-electrophile coupling reactions.

Application In Synthesis of 4,4′-Dibromobiphenyl

A number of groups have invested considerable time synthesizing double-decker silsesquioxane (DD SQ) copolymers; however, to our knowledge, no one has sought to explore through-chain electronic communication between DD SQs via conjugated co-monomers. We recently demonstrated that stilbene derivatives of simple DD cages exhibit properties commensurate with formation of cage centered lowest unoccupied molecular orbitals (LUMOs), equivalent to LUMOs found in complete/incomplete SQ cages, [RStilbeneSiO(1.5)](8,10,12), [RStilbeneSiO(1.5)](7)[O1.5SiMe/nPr], [RStilbeneSiO(1.5)](7)[O0.5SiMe3](3), [RStilbeneSiO(1.5)](8)[O-0.5-SiMe3](4), and [RStilbeneSiO(1.5)](8)[OSiMe2](2). Such LUMOs support the existence of 3D excited-state conjugation in these cages. We describe here Heck catalyzed copolymerization of vinyl(Me)SiO(PhSiO1.5)(8)OSi(Me)vinyl (vinylDDvinyl) with X-Ar-X, where X = Br or I and X-Ar-X = 1,4-dihalobenzene, 4,4’dibromo-1,1′-biphenyl, 4,4 ”-dibromo-p-terphenyl, 4,4′-dibromo-trans-stilbene, 2,5-dibromothiophene, 5,5′-dibromo-2,2′-bithiophene, 2,5-dibromothieno[3,2-b]thiophene, and 2,7-dibromo-9,9-dimethylfluorene. Coincidentally model analogs were synthesized from vinylMeSi(OMe)(2). All compounds were characterized in detail by gel permeation chromatography (GPC), matrix-assisted laser desorption/ionization-time-of-flight, thermogravimetric analysis, nuclear magnetic resonance, Fourier transfer infrared spectroscopy, ultraviolet-visible spectroscopy, photoluminescence spectrometry, and two-photon absorption (2PA) spectroscopy. Modeling of HOMO-LUMO energy levels of related compounds with R = Me rather than Ph was also explored. In the current systems, we again see apparent conjugation in excited states, as previously observed, as indicated by 50-120 nm red shifts in emission from the corresponding model silane compounds. These results suggest unexpected semiconducting behavior via vinylMeSi(O-)(2) (siloxane) bridges between DD cages in polymers. The thiophene, bithiophene, and thienothiophene copolymers display integer charge transfer behavior on doping with 10 mol % F(4)TCNQ supporting excited-state conjugation; suggesting potential as p-type, doped organic/inorganic semiconductors.

We report a new class of metal-organic framework (MOF) inks with a water-repellent, photocurable fluoropolyrner (PFPE) having up to 90 wt % MOF loading. These MOF inks are enabled to process various MOFs through spray coating, pen writing, stencil printing, and molding at room temperature. Upon UV curing, the hydrophobic PFPE matrix efficiently blocks water permeation but allows accessibility of chemicals into the MOF pores, thereby freeing the MOF to perform its unique function. Moreover, by introducing functional MOFs we successfully demonstrated a water-tolerant chemosensor for a class of aromatic pollutants in water and a chemical-resistant thermosensor for visualizing temperature image. This approach would open up innumerable opportunities for those MOFs that are otherwise dormant.

Constructing effective photocatalysts with visible light response to achieve rapid dehalogenation of polyhalogenated compounds remains a challenge nowadays. Herein, Pd nanoclusters-decorated TiO2 nanosheets with surface defects (Pd/TNS) are designed for polyhalogenated biphenyls dehalogenation under visible light. Pd/TNS is able to rapidly remove bromine atoms of 4-bromobiphenyl in 30 min. Experimental results reveal that oxygen vacancies and Ti3+ are in-situ generated in TNS during Pd photodeposition, which extend the absorption band edge of Pd/TNS to visible light region. Besides, the unique two-dimensional nanosheets structure of TNS contributes to a high surface area for high dispersion of Pd nanoclusters. Importantly, the Pd nanoclusters serve to activate carbon-halogen bond in polyhalogenated biphenyls and hydrogen-oxygen in H2O. The high dehalogenation efficiency could be assigned to a strong chemical interaction and synergistic effect between the Pd nanoclusters and TiO2(B) nanosheets. Finally, a collaborative mechanism is proposed for photocatalytic dehalogenation of polyhalogenated biphenyls on Pd/TNS.

Exciton binding energy has been regarded as a crucial parameter for mediating charge separation in polymeric photocatalysts. Minimizing the exciton binding energy of the polymers can increase the yield of charge-carrier generation and thus improve the photocatalytic activities, but the realization of this approach remains a great challenge. Herein, a series of linear donor-acceptor conjugated polymers has been developed to minimize the exciton binding energy by modulating the charge-transfer pathway. The results reveal that the reduced energy loss of the charge-transfer state can facilitate the electron transfer from donor to acceptor, and thus, more electrons are ready for subsequent reduction reactions. The optimized polymer, FSO-FS, exhibits a remarkable photochemical performance under visible light irradiation.

In this work, polymers comprising of the different ratios of N-decyl or N-triethylene glycol substituted 2,7-carbazoles and tetraphenylethenes were designed and synthesized by palladium-catalyzed Suzuki Miyaura cross coupling reaction of their corresponding comonomers. The copolymers containing carbazoles and tetraphenylethenes showed aggregation induced emission characteristics in both solid state and aggregate state when the composition of the tetraphenylethenes reached to 50%. N-triethylene glycol substituted carbazole polymers revealed lower bandgap and higher HOMO level compared to that of the N-decyl substituted carbazole polymers. The higher composition of the tetraphenylethenes, the deeper HOMO level and the larger bandgap of the polymers. Polymers with 1:1 molar ratio of the carbazoles and the tetraphenylethenes exhibited sphere-like nanoparticles with an average diameter of around 30 nm. The polymers containing carbazole and TPE units in 3:1 or 1:3 molar ratio self-assembled to form nanoaggregates with a size of around 100 nm.

Unsupported nanoporous gold (AuNPore) is a highly efficient, practically applicable, and recyclable catalyst for hydrodebromination of aromatic bromides. The AuNPore-catalyzed hydrodebromination of aromatic bromides proceeded smoothly at relatively low hydrogen pressure and temperature to achieve good to excellent yields of the corresponding non-bromine variants. The selective hydrodebromination reaction occurred exclusively in the coexistence of chlorine atom. For the first time, a mechanistic study revealed that the H-H bond splits in a heterolysis manner on the surface of AuNPore to generate Au-H hydride species.

Subsequently, novel electroactive aromatic poly(ether sulfone)s (PES), NTPPA-PES and NTPB-PES, could be obtained from silyl polycondensation. The PESs were readily soluble in commonly used laboratory organic solvents and could be solution-cast into tough and amorphous films with moderate levels of glass-transition temperature around 220 degrees C and thermal stability without significant weight loss up to 400 degrees C under nitrogen or air atmosphere. The Nernst equation method was used to explore the number of electrons transferred at each oxidation step of the targeted two monomers. Furthermore, these two anodic electrochromic PESs were introduced into electrochromic devices accompanied with cathodic heptyl viologen (HV), and the resulted devices demonstrated a high coloration contrast and excellent electrochemical stability.
