| Abstract: | There are few yellow colour anthraquinone dyes containing thio-ether group. As a yellow component for liquid crystal colour display, it shows hig-her order parameters. Anthraquinone thio-ether dyes, consisting of alkyl benzene, alkoxybenze-ne, carboxy-esterbenzene and halogen substituted benzene groups are prepa-red. The mole extinction coefficients of the dyes in chloroform are 8400 -11000. The maximum absorption wavelengths of dyes in liquid crystal E- 7 are 448-467 nm. The solubilities of them are less than 1.85%. The order parameters are 0.59-0.80. The order parameters of carboxy-esterbenzene type dyes are higher tham that of other series. |
