| 抄録: | A series of biphenyl-2, 2'-diylbis(diarylmethanol)s 3, which have two kinds of aryl groups at the bay region, were efficiently obtained by integrated flow microreactor synthesis. The diols 3NO/NX are the precursors of unsymmetric biphenylic dications 2NO/NX^[2+] which are transformed into the corresponding dihydrophenanthrenes 1NO/NX via 2NO/NX^[+•] upon reduction, when they exhibit two-stage color changes. On the other hand, the steady-state concentration of the intermediate 2NO/NX^[+•] is negligible during the oxidation of 1NO/NX to 2NO/NX^[2+], which reflects unique tricolor electrochromicity with a hysteretic pattern of color change [color 1→color 2→color 3→color 1]. |
