IPC: C07F15/00
Filed: 2020-12-17
Abstract: The present invention relates to a preparation method for and an application of a chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand SpiroPNP and an iridium catalyst Ir-SpiroPNP thereof. The chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand is a compound represented by formula I, or a racemate or optical isomer thereof, or a catalytically acceptable salt thereof; and the main structural feature is a phosphine ligand having a chiral spiroindene skeleton and a large sterically hindered substituent. The chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand can be synthesized into a chiral starting material from a 7-diaryl/alkylphosphino-7'-amino-1,1'-spirodihydroindenyl compound having a spiro ring skeleton. The iridium catalyst of the chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand is a compound represented by formula II, or a racemate or optical isomer thereof, or a catalytically acceptable salt thereof. The iridium catalyst can be used to catalyze the asymmetric catalytic hydrogenation of carbonyl compounds, and especially in the asymmetric hydrogenation of simple dialkyl ketones, said catalyst exhibits high yield (>99%) and enantioselectivity (up to 99.8%ee), thus having practical value.

Title: Timing advance control transmission in downlink control information for secondary cell group suspension
Inventor: CHENG PENG
IPC: H04W76/15
Filed: 2020-12-22
Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with both a master cell group (MCG) and a secondary cell group (SCG) and may transmit an uplink message to a primary secondary cell (PSCell) of the SCG after communications with the SCG have been suspended. Subsequently, the PSCell may respond with downlink control information (DCI) that includes timing advance (TA) information for the UE to use for subsequent communications with the SCG. In some cases, the UE may transmit a random access message to the PSCell to reestablish communications with the SCG, and the PSCell may respond with DCI that includes the TA information. Additionally or alternatively, the UE may transmit a preconfigured uplink message to the PSCell, and the PSCell may respond with DCI as an acknowledgment message, where the DCI includes the TA information.

Abstract: An aqueous binder for a lithium ion battery, a preparation method therefor, and a lithium ion battery pole piece, which relate to the technical field of lithium ion batteries. The binder comprises cross-linked polyrotaxane and linear polymers that have DMAPS segments, and the polyrotaxane is obtained by self-assembling cyclodextrin and polyethylene glycol supramolecules and then endcapping. By means of introducing a zwitterionic structure of DMAPS, the same structural unit of the binder comprises both anions and cations, which may form a unique supramolecular switch structure that has dynamic reversible characteristics. Moreover, the linear polymers may form a pulley structure after cross-linking with polyrotaxane. The structure is highly ordered and has a 3D network structure, and has good flexibility and a self-healing function. At the same time, zwitterions may promote electron delocalization. Sulfonic acid groups are easily attacked by electrophilic groups, and interact easier with lithium ions that have low electron cloud density, which promotes the dissociation of lithium salts and forms new lithium ion migration channels, thereby achieving the effect of improving ion conductivity.
