Abstract
NEW MATERIAL:A compound expressed by formula I or formula II [R1, R3 and R5 are H, F, Cl, Br, CN, methyl, ethyl, methoxy, ethoxy or CF3; R2, R4 and R6 are H, F, Cl, Br, CN, NO2, CF3, nonafluorobutyl, R7, OR7, SR7, SO2R7, COR7, or (CH2)mCO2R7 (R7 is 1-12C alkyl which may be substituted; m is 0-2), etc.]. USE:The above-mentioned compound exhibits strong absorption in near-infrared area and useful as a material for optical disc memory or for thermally writable liquid crystal element. PREPARATION:A compound expressed by formula III (X is Cl or Br) is thermally reacted with an orthoaminothiophenol derivative expressed by formula IV as necessary in the presence of an acid bonding agent to provide the compound expressed by formula I or formula II. The compound expressed by formula I is obtained as a main product at reaction temperature of 100-160 deg.C and the compound expressed by formula II is obtained as a main product at 180-220 deg.C and equivalent mixture of the both is obtained at 160-180 deg.C.
