“…148,161 Based on EIS measurements, it has been concluded that the star-shaped morphology facilitates ion diffusion compared to the linear structure, which in turn results in a substantially lower intrinsic resistance. 47,131 The resistance values are calculated using Zview software: 173.40 Ω for linear NH 2 -(ANI) 4 -COOH, 50.39 Ω for para-bi-(ANI) 4 -COOH, 37.74 Ω for meta-bi-(ANI) 4 -COOH, and 33.68 Ω Tri-(ANI) 4 -COOH films. EIS can be used to investigate the effects of the molecular architecture on the electrochromic efficiency, and modelling can increase the ambiguity in the interpretation of the EIS results.…”
