  摘要：

  A procedure was developed for the synthesis of dimethyl 2-fluoro- and 2,2 '-difluorobiphenyl-4-4 '-dicarboxylates. The latter were converted into fluorinated 4,4 ' bis[(E)-2-(1,3-benzoxazol-2-yl)ethenyl]- and 4,4 '-bis[5-(4-octyloxyphenyl)-1,3,4-oxadiazol-2-bl]biphenyls which showed strong luminescence in the crystalline state and in solution their spectral properties were examined.
