In this study, the electrochromic behavior of benzonitrile compounds were investigated. For this, a series of benzonitrile compounds with different chemical structures were synthesized and their electrochemical properties were investigated by cyclic voltammetry. Electrochromic behavior of the benzonitrile derivatives were also investigated by constructing sandwich type electrochromic devices and recording the changes in the UV-vis spectra as a function of applied potential. The compounds exhibited excellent electrochromic properties such as a high optical contrast, low driving voltage, good switching stability, high coloration efficiency, and a fast response time. All five compounds had different colors (orange, yellow-green, reddish-brown, green, blue) and driving voltages that were highly dependent on their chemical structures. The results indicate that benzonitriles are good electrochromic materials and should be of interest for applications such as electrochromic smart windows, information displays, and optical storage devices.

Aryl sulfones and phosphine oxides are widely used as molecular building blocks for host materials in the emissive layers of organic light-emitting diodes. In this context, the chemical stability of such molecules in the triplet state is of paramount concern to long-term device performance. Here, we explore the triplet excited-state (T-1) chemical stabilities of aryl sulfonyl and aryl phosphoryl molecules by means of UV absorption spectroscopy and density functional theory calculations. Both the sulfur-carbon bonds of the aryl sulfonyl molecules and the phosphorus-carbon bonds of aryl phosphoryl derivatives are significantly more vulnerable to dissociation in the T-1 state when compared to the ground (S-0) state. Although the vertical S-0 -> T-1 transitions correspond to nonbonding -> pi-orbital transitions, geometry relaxations in the T-1 state lead to sigma-sigma* character over the respective sulfur-carbon or phosphorus carbon bond, a result of significant electronic state mixing, which facilitates bond dissociation. Both the activation energy for bond dissociation and the bond dissociation energy in the T-1 state are found to vary linearly with the adiabatic T-1-state energy. Specifically, as T-1 becomes more energetically stable, the activation energy becomes larger, and dissociation becomes less likely, that is, more endothermic or less exothermic. While substitutions of electron-donating or -accepting units onto the aryl sulfones and aryl phosphine oxides have only marginal influence on the dissociation reactions, extension of the pi-conjugation of the aryl groups leads to a significant reduction in the triplet energy and a considerable enhancement in the Ty-state chemical stabilities.

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.

A series of three fluorine containing and three non-fluorinated Diels-Alder step-growth polyarylene polymers and copolymers was synthesized via conventional oil bath heating (days/weeks). A drastic time reduction was realized with a microwave-assisted polymerization (hours). The polymers were characterized by multinuclear (H-1,C-13, and(19)F) NMR and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, thermal analysis (thermogravimetric analysis [TGA], differential scanning calorimetry [DSC], and dynamic mechanical analysis [DMA]), gel permeation chromatography, X-ray diffraction (XRD), water contact analysis, and refractive index (RI) measurements. The NMR spectra indicated a mixture ofparaandmetaconformations through the polymer backbone increasing to moreparawith greater fluorine content. TGA revealed the fluorine-containing polyarylenes possessed the highest char yields at almost 80% at 1000 degrees C under nitrogen, and all the polyarylenes possessed onset of degradation temperatures above 550 degrees C under nitrogen and air atmospheres. XRD analysis indicated more ordering for the fluorine-containing polyarylenes which afforded the high char yields. DMA gave storage moduli values in the range of 1-10 GPa for the polyarylenes. Molecular weights for all samples were above 100 kg/mol. Water contact angles did not change with fluorine content due to the shielding effect of the pendant phenyl groups. However, the RI decreased to 1.6497 at 632.8 nm for the polyarylene with the highest fluorine content.

The reversible transformation of multicomponent nanorotors (ROT-1,k(298)= 44 kHz orROT-2,k(298)= 61 kHz) to the dimeric supramolecular structures (DS-1orDS-2,k(298)= 0.60 kHz) was triggered by a stoichiometric chemical stimulus. Simple coordination changes at the central phenanthroline of the molecular device by altering metal ions (Cu+-> Zn2+) or stoichiometry (Cu+, 1 equiv. -> 0.5 equiv.) affected the terminal zinc(ii) porphyrin units, the active sites within the machinery, changing rotational, catalytic and optical properties. In presence of added pyrrolidine, the nanorotorROT-1was inactive for catalysis whereas formation of the dimeric supramolecular structuresDS-1initiated a Michael addition reaction by releasing the organocatalyst from the porphyrin sites. This catalytic machinery (ROT-1 reversible arrow DS-1) proved to reproducibly work over two full cycles using allosteric OFF/ON control of catalysis.

In this study, synthesis, characterization and photocatalytic performance of surface-modified TiO2 nanoparticles with ascorbic acid-stabilized Pd nanoparticles are presented. The structure, composition and morphology of as-prepared nanophotocatalyst were characterized by UV-DRS, FT-IR, ICP-AES, TEM and XPS analysis. Ascorbic acid-stabilized Pd nanoparticles induced visible light driven photocatalytic property on the surface of TiO2 which are otherwise insensitive to visible light owing to the wide band gap. The catalytic system worked well for the Suzuki-Miyaura cross-coupling and Ullmann homocoupling under compact fluorescent light as a visible source with significant activity, selectivity and recyclability. Good to excellent yields of biaryl products were obtained for various aryl halides having different electronic demands and even aryl chlorides. Our results proposed that the improved photoactivity predominantly benefits from the synergistic effects of ascorbic acid-stabilized Pd nanoparticles on TiO2 nanoparticles that cause efficient separation and photoexcited charge carriers and photoredox capability of nanocatalyst. Thus, tuning of band gap of TiO2 making a visible light sensitive photocatalyst, demonstrates a significant advancement in the photocatalytic Suzuki-Miyaura and Ullmann coupling reactions.

A Lewis base catalyst Trip-SMe (Trip = triptycenyl) for electrophilic aromatic halogenation using N-halosuccinimides (NXS) is introduced. In the presence of an appropriate activator (as a noncoordinating-anion source), a series of unactivated aromatic compounds were halogenated at ambient temperature using NXS. This catalytic system was applicable to transformations that are currently unachievable except for the use of Br-2 or Cl-2: e.g., multihalogenation of naphthalene, regioselective bromination of BINOL, etc. Controlled experiments revealed that the triptycenyl substituent exerts a crucial role for the catalytic activity, and kinetic experiments implied the occurrence of a sulfonium salt [Trip-S(Me)Br][SbF6] as an active species. Compared to simple dialkyl sulfides, Trip-SMe exhibited a significant charge-separated ion pair character within the halonium complex whose structural information was obtained by the single-crystal X-ray analysis. A preliminary computational study disclosed that the pi system of the triptycenyl functionality is a key motif to consolidate the enhancement of electrophilicity.

Developing efficient and wide spectrally acting photocatalysts for light-driven hydrogen production from water is highly desirable for solar energy conversion. Herein, diketopyrrolopyrrole (DPP) is used to combine with triphenylamine (TPA), bipyridyl (bdy), and biphenyl (bph) units for construction of conjugated microporous polymer photocatalysts. Although the synthesized two polymers, DPP-bdy-TPA and DPP-bph-TPA, have a similar framework structure, the former bearing a hydrophilic , bipyridyl unit displays much better photocatalytic performance with hydrogen production rates of 6918 and 2780 mu mol g(-1) h(-1) under a full-arc xenon lamp and visible light (>440 nm) illumination, respectively. Moreover, DPP-bdy-TPA has a wide photoaction spectrum with apparent quantum yields of 9.60% at 420 nm, 7.32% at 500 nm, and 0.31% at 600 nm, the so high values rarely achieved by present-known organic semiconductor photocatalysts. These results undoubtedly prove DPP is an excellent building block, and this work well exemplifies its utilization for construction of high-performance photocatalysts.
