“…(Figure 1(a)). [2][3][4][5][6][7][8][9][10][11][12][13][14] To improve the processing capability or control the electronic properties of aniline, various substitution strategies have been investigated. For example, the polymerization of diphenylamine (DPA), which can be processed through the 4,4 0 -phenylphenyl coupling mechanism, yields PDPA having various attractive properties such as electrochemical activity, electrochromism, and conductivity.…”
