Novel diamine compound, preparation method and applications thereof

The invention relates to a novel diamine compound, a preparation method and applications thereof, wherein the diamine compound can improve the efficacy of a liquid crystal display element, and polyamide acid, polyimide and a liquid crystal alignment agent prepared from the diamine compound all have good chemical stability, good thermal stability and other properties, so that the formed liquid crystal alignment film has high pre-tilt angle.

Isolation of Novel Radical Cations from Hydroquinone Ethers. Conformational Transition of the Methoxy Group upon Electron Transfer

Hydroquinone ethers as the bis-annulated derivatives R1-R3 are excellent electron donors by virtue of the facile oxidation to their radical cations R1.(1+), R2.(1+), and R3.(1+) that are readily isolable as unusually robus
