“…n‐ Buthyllithium solution (2.4 m in hexanes) was purchased from J&K Scientific Ltd. Potassium carbonate was purchased from Alfa Aesar. 2,3‐Dibromo‐benzo[ b ]thiophene, 3‐bromo‐2‐(thiophen‐2‐yl)benzo[ b ]thiophene, Spiro‐Bn , and tetrakis(triphenylphosphine)palladium(0) as catalyst for Suzuki as well as Negishi cross‐coupling and dichlorobis(triphenylphosphine)palladium(II) as catalyst for Sonogashira coupling were synthesized according to the literature procedures with slight modifications. Tetrahydrofuran and dichloromethane for reactions were purified with the PureSolv MD 5 solvent purification system before use.…”

A series of air-stable spiro-fused ladder-type boron(III) compounds has been designed, synthesized, and the electrochemistry and photophysical behavior have been characterized. By simply varying the substituents on the pyridine ring and extending the π-conjugation of the spiro framework, the emission color of these compounds can be easily fine-tuned spanning the visible spectrum from blue to red. All compounds exhibit a broad and structureless emission band across the entire visible region, assigned as an intramolecular charge-transfer transition originating from the thiophene of the spiro framework to the pyridine-borane moieties. In addition, these compounds demonstrate high photoluminescence quantum yields of up to 0.81 in dichloromethane solution and 0.86 in doped thin films. Some of the compounds have also been employed as emissive materials, in which solution-processed organic light-emitting devices (OLEDs) with tunable emission colors spanning the visible spectrum from blue, green to red have been realized, demonstrating the potential applications of these boron compounds in OLEDs.

“…The catalyst Pd(PPh 3 ) 4 was synthesized according to a literature reference and stored under argon atmosphere in a refrigerator. 38 Diethyl ether (Et 2 O) was freshly distilled from sodium each time prior to the reaction. Solvent (DME/water, 4:1) employed in Suzuki couplings was always degassed with argon prior to utilization.…”

Indolinooxazolidine: A Versatile Switchable Unit

et al. 2014

The design of multiresponsive systems continues to arouse a lot of interest. In such multistate/multifunctional systems, it is possible to isomerize a molecular system from one metastable state to another by application of different stimulation such as light, heat, proton, or electron. In this context, some researches deal with the design of multimode switch where a same interconversion between two states could be induced by using indifferently two or more different kind of stimuli. Herein, we demonstrate that the association of an indolinooxazolidine moiety with a bithiophene unit allows the development of a new trimode switch. A reversible conversion between a colorless closed form and a colorful open form can be equally performed by light, proton, or electrical stimulation. In addition, the oxidation of this system allows the generation of a third metastable state.

“…The residue was purified by column chromatography on alumina (ethyl acetate/cyclohexane, 9/1, v/v). (9) To a solution of the appropriate iodinated compound (1.14 mmol) in anhydrous toluene (25 mL), beforehand degassed under argon, were successively added, hexabutylditin (783 mL, 1.55 mmol) and freshly prepared tetrakis(triphenylphosphine) palladium(0) [47] (33 mg, 28.6 mmol). The resulting solution was refluxed for 2e14 h under argon.…”
