The electrical properties of organic semiconductors (OSCs), whether they are conjugated small molecules or polymers, can be tailored by incorporating electrically insulating units (EIUs), which are organic moieties consisting of nonconjugated units. EIUs can be introduced to a thin film by synthetically connecting them to the otherwise conjugated OSC molecules or by blending them in as separate EIU molecules with the OSCs during the thin‐film fabrication process. The engineered EIUs are capable of imparting various additional functions to the OSC thin film and improving their electrical properties. In this review article, a comprehensive overview of various effects of EIUs on OSC thin films and their consequent electrical performance when used as active layers in organic field‐effect transistors (OFETs) is provided. A broad range of studies of the synthetic approaches of incorporating EIUs, such as those using side chains, block copolymers, and conjugation‐break spacers, and of the blending approaches with organic insulators is discussed. Finally, a brief summary and perspectives for future research in this field are presented.

“…In recent years, many studies related to bianary, ternary, and quaternary azeotropic mixtures have been developed, which provided accurate thermodynamic data for separation. Besides thermodynamic data, several methods have developed to overcome this problem, such as pressurized distillation, azeotropic distillation, extraction, membrane separation, and so on . For example, azeotropic distillation was used to separate azeotropic mixtures instead of extractive distillation in Japan catalytic chemical (NSKK) technology; BASF company used special solvents to break azeotropes through extraction.…”

The design and optimization of the separation process of acrylic acid and corresponding esters in formaldehyde aqueous solution was systematically researched in this work. Thermodynamics was provided for formaldehyde, acrylic acid, and corresponding esters system according to the particularly. On basis of the thermodynamics, optional separation sequence and separation technology were designed, which reduced separation complexity and search scope. In addition, system integration including process optimization and energy integration were optimized in detail in the procedure. The proposed systematic procedure was applied to acrylic acid and corresponding esters production using methyl acetate and formaldehyde as raw materials. The systematic procedure provided a significant guidance for the separation of the formaldehyde, acrylic acid, and corresponding esters.

“…Its usage is facilitated by its low toxicity, high biodegradability and low persistence [1]. DMC can be used in industry mainly as a fuel additive [2], precursor for synthesis of carbonic acid derivatives, methylating agent [3], methyl sulphate exchanger [4], or an intermediate in the synthesis of polycarbonates and isocyanates [5], carbonylating agent [6], alkylating agent, polar solvent [7], component in the synthesis of polyurethane [8].…”

The catalytic activity of Norit supported Cu, Ni and Cu-Ni catalysts was investigated in the synthesis of dimethyl carbonate (DMC) by the oxidative carbonylation of methanol. Cu/Norit showed the best catalytic activity. The reaction was carried out in a continuous flow system at atmospheric pressure usually at 393 K. The main products were methyl formate, DMC and CO 2 . The methanol conversion on Cu/Norit achieved in steady state was about 22 % and the DMC yield 13.2 %. Based on the XPS data we can establish that copper reduced to its metallic form during reduction but oxidized in the reaction mixture, and is mostly in the Cu ? state, with some Cu 2? . It is possible that the DMC formation rate depends on the surface concentration of oxidized Cu and on the ratio of Cu ? and Cu 2? . Based upon the IR measurements adsorbed DMC was found on the surface of the Cu/Norit catalyst during the catalytic reaction.
