Synthesis of substituted 4,4´-dihalobiphenyls and their use for the preparation of isomeric bis(carbazolyl)biphenyls

Abstract

Model compounds of some polychlorobiphenyl congeners, viz., 4,4´-dihalobiphenyls, were synthesized. These compounds can be successfully utilized by a chemical method for the in situ generation of arynes followed by the reaction with carbazole in order to prepare appropriate bis(carbazolyl)biphenyls as components for molecular electronics and OLED devices.
