Novel optically active benzene derivatives, process for producing the same and liquid-crystalline substances containing said derivatives as active ingredient and optical switching elements |
| abstract |
Disclosed are novel active benzene derivatives represented by the general formula (I): ##STR1## (wherein X represents --COO--, --OCO--, --CH 2 O-- or --OCH 2 --; A represents a hydrogen atom, a halogen atom or an alkyl or alkoxyl group having 1 to 20 carbon atoms; R represents an alkyl group having 1 to 20 carbon atoms; l and m each represents a number of 1 or 2, n represents a number of 0 or 1, but when n is 0 the sum of l and m is 3 or less; and * indicates asymmetric carbon atom), a process for producing the same, liquid-crystalline substances containing said derivatives as active ingredient, and optical switching elements utilizing the liquid crystal compositions containing said liquid-crystalline substances. |
