Electron donor compound and preparation method thereof, light emitting device and display device

The invention relates to an electron donor compound, a light-emitting device, a preparation method of the light-emitting device and a display device. The electron donor compound has the following structural groups: each R1 independently selected from hydrogen, a trimethylsilyl group, a cyclohexyl group, a 3-pentyl group, a 4-(9,9'-spirobifluorene) group, a 2-(9,9'-diphenyl fluorene) group or a tetraphenyl vinyl group, wherein each R1 is not hydrogen at the same time. When the electron donor compound provided by the invention is used as an electron donor material to be applied to an interface heterojunction exciplex system, the original contact point of an electron donor and an electron acceptor is isolated by a non-hydrogen substituent, so that electrons and holes are separated in space, according to the invention, electrons of the electron acceptor layer can be prevented or hindered from easily moving into the electron donor layer, so that the electrification problem of quantum dots is avoided or relieved, and the efficiency and the service life of the light-emitting device are improved.

Hydrogenation of Borylated Arenes

A cis-selective hydrogenation of abundant aryl boronic acids and their derivatives catalyzed by rhodium cyclic (alkyl)(amino)carbene (Rh–CAAC) is reported. The reaction tolerates a variety of boron-protecting groups and provides direct access to a broad s

SYNTHESIS OF BORONIC ESTERS AND BORONIC ACIDS USING GRIGNARD REAGENTS

Boronic esters and boronic acids are synthesized at ambient temperature in an ethereal solvent by the reaction of Grignard reagents with a boron-containing substrate. The boron-containing substrate may be a boronic ester such as pinacolborane, neopentylglycolborane, or a dialkylaminoborane compound such as diisopropylaminoborane. The Grignard reagents may be preformed or generated from an alkyl, alkenyl, aryl, arylalkyl, heteroaryl, vinyl, or allyl halide compound and Mg°. When the boron-containing substrate is a boronic ester, the reactions generally proceed at room temperature without added base in about 1 to 3 hours to form a boronic ester compound. When the boron-containing substrate is a dialkylaminoborane compound, the reactions generally proceed to completion at 0°C in about 1 hour to form a boronic acid compound.
