The first asymmetric catalytic approach to multilayer 3D chirality has been achieved by using Suzuki-Miyaura cross-couplings. New chiral catalysts were designed and screened under various catalytic systems that proved chiral amide-phosphines to be more efficient ligands than other candidates. The multilayer 3D framework was unambiguously determined by X-ray structural analysis showing a parallel pattern of three layers consisting of top, middle and bottom aromatic rings. The X-ray structure of a catalyst complex, dichloride complex of Pd-phosphine amide, was obtained revealing an interesting asymmetric environment nearby the Pd metal center. Three rings of multilayer 3D products can be readily changed by varying aromatic ring-anchored starting materials. The resulting multilayer products displayed strong luminescence under UV irradiation and strong aggregation-induced emission (AIE). In the future, this work would benefit not only the field of asymmetric synthesis but also materials science, in particular polarized organic electronics, optoelectronics and photovoltaics.
Compound and application thereof

Paragraph 0091-0093, (2021/06/23)
The invention relates to a compound and application thereof. The compound has a structure represented by formula I shown in the specification. The compound provided by the invention takes a 7-membered conjugated aromatic ring as a parent nucleus structure, a substituent group must contain one carbazole and a derivative group (Ar) thereof, carbazole ensures a corresponding HOMO energy level and provides good hole capability, and the addition of the 7-membered aromatic ring provides a larger planar conjugated group, so that the carrier mobility of the whole molecule is increased, and the hole mobility is improved. Moreover, due to the introduction of the rigid structure, the material has high glass transition temperature and excellent thermal stability, can effectively improve the device efficiency and reduce the driving voltage when being applied to OLED devices, and is especially a good hole-type main body material.
