The invention discloses a preparation method of N-arylcarbazole-3-boric acid, and belongs to the field of liquid crystal intermediates. The preparation method comprises the following steps: coupling carbazole with aryl halide in the presence of alkali to generate N-arylcarbazole, enabling the N-arylcarbazole to react with a bromination reagent to generate Naryl-3, 6-dibromo carbazole, enabling theNaryl-3, 6-dibromo carbazole to react with borate and butyl lithium by a one-pot method, and carrying out hydrolyzing to obtain N-arylcarbazole-3-boric acid. According to the method, dibromides whichare easy to purify are generated during bromination, monosubstituted products are generated by controlling the using amount of the lithiation reagent and the boric acid ester during lithiation, the method is verified on the scale of dozens of kilograms, and the method has the prospect of industrial methods.

An object of the present invention is to provide a novel concept coadsorbent that can be used instead of conventionally-used deoxycholic acid (DCA). The present invention provides a coadsorbent having hole conduction characteristics, including the compound represented by Formula 3, and provides a dye-sensitized solar cell including a light absorbing layer including the coadsorbent having hole conduction characteristics. The photocurrent and photovoltage of the dye-sensitized solar cell can be improved because it includes a light absorbing layer including the coadsorbent having hole conduction characteristics.
