Abstract
NEW MATERIAL:A 2,6-Di(4'-alkylpiperidino)anthraquinone expressed by formulaI(R1 and R2 are 1W8C alkyl).
EXAMPLE: 2,6-Di(4'-n-propylpiperidino)anthraquinone.
USE: An anthraquinone and a material for liquid crystal display apparatuses or sensors, exhibiting the liquid phase, having a high solubility, and capable of changing the light absorption, photoconductivity, electric conductivity and photoelectromotive force by changing the temperature, applying an electric field, and a magnetic field.
PROCESS: A compound expressed by formula II is reacted with a compound expressed by formula III in a nonpolar solvent, e.g. xylene, in the presence of a weak base, e.g. sodium bicarbonate, at 50W200°C to give the compound of formulaI[R1 and R2 are R (R is 1W8C alkyl or 1W8C alko]yl)].
