Four organic photosensitizers incorporating a carbazole or 3,6-diiodocarbazole unit as the electron donor, a benzene/thiophene or oligothiophene moiety as the conjugated spacer, and 2-cyanoacrylic acid as the electron acceptor have been synthesized. The p

Paragraph 0100-0101; 0105, (2020/12/08)
The invention provides a compound shown as a general formula (I), which can be used for an organic electroluminescent device as a hole transport material. The compound has fluorene-substituted and arylamine and carbazole-substituted phenyl arylamine parent structures, is high in interatomic bond energy and high in thermal stability, facilitates intermolecular solid-state accumulation and is high in hole transition capacity. When the compound is applied to a hole transport layer, a proper energy level is formed between the compound and an adjacent layer, hole injection and migration are facilitated, and the driving voltage can be effectively reduced; meanwhile, the hole migration rate is relatively high, and the light-emitting efficiency of a device can be effectively improved. The invention also provides the hole transport material containing the compound shown in the general formula (I), an organic electroluminescent device and a display device.

Functionalized ynones can be activated by Tf2C=CH2, which was generated in situ, to form zwitterionic species. These species were trapped in an intramolecular fashion by several nucleophiles to generate two major types of triflones in a divergent manner. Through fine-tuning of the reaction temperature, bis(triflyl)-6-membered- or (triflyl)-5-membered-fused-heterocycles were achieved in reasonable yields in a totally selective manner. In this way, bis(triflyl)flavones, bis(triflyl)thioflavones, bis(triflyl)selenoflavones, (triflyl)benzothienopyrans, (triflyl)benzoselenophenopyrans, (triflyl)vinyl aurones, and (triflyl)pyranoindoles were constructed. Conceivable mechanistic pathways were suggested on the basis of the isolation of several intermediates and the results from control experiments.
