-
Paragraph 0030; 0031, (2019/03/08)
The invention relates to an organic aromatic amine luminescent material containing a seven-membered ring, and belongs to the technical field of organic photoelectric materials. An organic compound with organic aromatic amine having the seven-membered ring as a core structure is used for an OLED device as a light-emitting layer or an electron transfer layer material. The material has good molecularstability, and the prepared OLED device has superior photoelectric performance, high thermal stability, low driving voltage and high efficiency. The service life of the device can be prolonged, and the requirements of device manufacturers can be met.

A new family of host molecules, based on the singly bridged triarylmethanol and triarylacetic acid frameworks, is described.These hosts form crystalline inclusions with a variety of uncharged organic molecules ranging from protic dipolar to apolar compounds (130 different species).The formation and stoicheiometry depend in a systematic manner on structural parameters of the host, such as the nature of the functional group and the substituents, and on the substituent positions.The crystal structures of three inclusion compounds have been studied by X-ray diffraction.They reveal the building principles of the new inclusion family.In the crystals of 1a*benzene (8:3), the benzene is interstitially entrapped by H-bonded tetramer clusters of 1a.Crystals of 1a*dioxane (4:3) are built of H-bonded 2:1 host-guest complexes including interstitial molecules of dioxane.In the case of 4c*EtOH (1:1), the building principle is formation of 2:2 host-guest clusters via a twelve-membered H-bonded ring.
