“…19,20 To improve the electrochemical property, the pristine PBI-CB film as prepared was annealed in vacuum at 50 °C for 2 h, which is a method used by others before. 21 The results are depicted in Figure 2c. Figure 2c exhibits the CV curve of the annealed PBI-CB film recorded in the same conditions as aforementioned.…”

The widespread application in displays, information encryption, and sensors has boosted studies of electrochromic (EC) systems combining large contrast, fast response, high robustness, and low-cost properties. Herein, we report a filmtype new EC system with a non-planar perylene bisimidecarborane derivative (PBI-CB) as the electroactive materials. It was revealed that the film demonstrated outstanding EC properties with response times of 1.18 and 0.94 s for the coloration and bleaching processes, respectively, large transmittance variation around 630 nm (45.7%), and superior stability for more than 200 coloration-bleaching cycles. Moreover, the film also showed precious electrofluorochromic (EFC) properties. The emission around 650 nm at the "on" state could be more than 24.5 times than that at the "off" state, and the response times of the off and on processes could reach 2.2 s and 4.3 s, respectively. Considering the facts that the film was fabricated via simple drop-coating, the EC/EFC operation was performed via a routine three-electrode system and the voltage applied is only −1.3 V, we believe that the EC/EFC system as developed would find applications in smart windows, information encryption, optoelectrical sensing, etc. In addition, the work could also pave the way for developing combined EC/EFC systems via employing known organic fluorophores as the electrochemical active materials, which are not only abundant in numbers but also solution-processable.

“…In contrast, crystalline films have advantages in cycling performance due to their structural stability. 25,[138][139][140] Therefore, researchers hope to prepare high EC performance NiO films by combining the stability of crystalline structure with the fast response and high optical modulation of amorphous structure. Li et al fabricated crystalline-amorphous double-layered NiO films through RF magnetron sputtering technology.…”
