Substituted phenyl-benzimidazo compounds are disclosed in which the phenyl group which is attached to the two position of the imidazo ring contains a carboxylic acid group, or derivatives thereof, para to the point of imidazo attachment. The benzimidazo is substituted in the 5,6 positions with amino groups or derivatives thereof. The compounds are particularly useful as AB-monomers in the preparation of poly [(2,6-imidazobenzimidazo)1,4-phenylene].
本文披露了取代苯基苯并咪唑化合物,其中连接到咪唑环的2位的苯基含有一个羧酸基团或其衍生物,与咪唑连接点相对的位置为邻位。苯并咪唑在5,6位被氨基基团或其衍生物取代。该化合物特别适用于制备聚[(2,6-咪唑苯并咪唑)1,4-苯基]的AB型单体。
