Structure and Isomerism of 2-(3-Substituted) Quinoxalinylhydrazones of Isatin and Its Homologs

Mono- and dihydrazones, the structure of which were established by means of 1H and 13C NMR, IR, and electronic absorption spectroscopy, were synthesized by reaction of 3-chloro-2-hydrazino- and 2,3-dihydrazinoquinoxalines with 1H-indole-2,3-dione and its 1-methyl and 1-butyl homologs.Thermal and photochemical conversion of the E, Z isomer to the Z isomer is observed, while the reverse transformation is observed in the case of treatment with alkali.

Thiophene-functionalized octupolar triindoles: Synthesis and photophysical properties

Two thiophene-functionalized octupolar triindole molecules were synthesized through Suzuki and Sonogashira cross-coupling reactions. Their photophysical and electrochemical properties were explored. The spectroscopic data demonstrate that triindole is an

Fluorine-substituted indolo-thiadiazoloquinoxaline-based D-A type polymers for photovoltaic applications

Two D-A type conjugated polymers, in which the electron-donating benzodithiophene monomers are connected to the electron-accepting indolo-thiadiazoloquinoxaline (ITQ) monomers via a thiophene bridge, are synthesized under Stille coupling conditions. Once the reference PB-ITQ is prepared, one fluorine atom is incorporated into the ITQ unit of PB-ITQ to afford the additional target polymer PB-ITQF. An inverted-type device with the configuration of indium tin oxide (ITO)/ZnO/Polymer:PC71BM/MoO3/Ag is utilized to examine the photovoltaic properties of the two polymers. Owing to the positive contributions of fluorine atoms, all the photovoltaic parameters of the device based on PB-ITQF such as the short-circuit current density, open-circuit voltage, and fill factor are improved as compared with those of the device based on PB-ITQ. As a result, the highest PCE of 2.32% is achieved from the fullerene-based polymer solar cell based on PB-ITQF.

Palladium-Catalyzed Cascade Hydrosilylation and Amino-Methylation of Isatin Derivatives

We demonstrate that using palladium acetate as a catalyst for reduction of DMF and isatin derivatives by hydrosilanes, a cascade hydrosilylation and amino-methylation reaction can be realized. With DMF as a reactant and a solvent, the in-situ generated siloxymethylamine intermediate, an adduct of DMF and hydrosilanes, smoothly participates in the successive stages, providing a serials of Si, N-functionalized indolin-2-ones in moderate to good yields. This strategy exhibits high chemoselectivity toward carbonyl moieties reduction among the substrates. (Figure presented.).
