    摘要: Anthraquinone dyes of the general formula: ##STR1## wherein R.sup.1, R.sup.3, R.sup.4 and R.sup.6 are selected from the group consisting of H, OH, OCH.sub.3, NO.sub.2, NH.sub.2 and NHCH.sub.3 ; R.sup.2 and R.sup.5 are selected from the group consisting of:(a) alkyl-, aryl-, alkaryl-, alkoxyaryl-, aminoaryl-, alkylaminoaryl-, dialkylamino-, arylaminoaryl- or ##STR2## wherein R.sup.7 is selected from the group consisting of alkyl-, aryl-, amino-, alkylamino-, dialkylamino-, arylamino-, alkyloxy-, and aryloxy radicals,along with their syntheses routes are disclosed. The dyes are particularly useful in liquid crystal displays which function with a "guest host" effect or in other electrooptical display devices having a medium therein switchable between different ordering states.
