5.37 g (20 mmol) of N,N,N′-triethylbenzidine obtained by reacting benzidine and 3 equivalents of ethylchloride were dissolved in 50 ml of methylene chloride, and 20 ml of a methylene chloride solution of 2.30 g (22 mmol) of methacrylic chloride were added dropwise thereto in the presence of triethylamine. After the resulting reaction solution was mixed with water to remove the water-soluble substances and the water was removed with sodium sulfate, the solvent was distilled out thereby obtaining 6.34 g (18 mmol) of N-methacryloyl-N,N′,N′-triethylbenzidine (electrochromic compound). The structure of the electrochromic compound is as follows:
