“…However, after a certain number of cycles, the EC materials usually suffer from alterations in their crystal structure or side relations, leading to degradation in the performance when switching color. 43,44 Therefore, multicolor EC devices should be reversible up to ten thousand cycles, or even more.

“…Xie et al 11 prepared a high-performance non-fullerene organic solar cell by embedding tetrahydroxy PBI in a zinc oxide thin film. This year, Wang et al 20 prepared a metal−organic framework (Mg-PDI) through a one-step hydrothermal process, which had good stability and coloring efficiency and could achieve simple patterning. However, this preparation method is harsh, timeconsuming, and energy-consuming, coupled with the inability to achieve large area/scale preparation and a fine pattern that seriously hinders the practical application of PBIs in EC devices.…”

The composite or hybrid of organic and inorganic materials is one of the common ways to improve the properties of photoelectric functional materials. Perylene bisimide (PBI) derivatives, as large π-conjugated organic small molecules, are a class of photoelectric functional materials with excellent performance. However, there were few reports on PBIs in the electrochromic field due to the difficulty of film-forming caused by their generally poor solubility. Here, water-soluble PBI derivatives (PDI-COOH and PCl-COOH) were synthesized. The hybrid films (ZnO@PDI-COOH/ PCl-COOH) formed by the coordination bond and π−π stacking were prepared via a simple solution immersion method. Fourier transform infrared spectrometry and X-ray diffraction as well as scanning electron microscopy, and energy-dispersive spectrometry results further confirmed the formation of hybrid films. At the same time, electrochemical and spectroelectrochemical analyses revealed that the films have reversible redox activity and cathodic electrochromic properties, which can change from orange-red to purple. The ZnO@PDI-COOH hybrid film formed by coordination bonds exhibits fast switching times (1.7 s colored time and 2.6 s bleached time), good stability (retain 92.41% contrast after 2400 cycles), a low driving voltage (−0.6−0 V), and a high coloration efficiency (276.14 cm 2 /C). The corresponding electrochromic devices also have good electrochromic properties. On this basis, a large-area (100 mm × 100 mm) electrochromic display device with fine patterning was fabricated by using the hybrid film, and the device shows excellent reversible electrochromic performance. This idea of constructing organic−inorganic hybrid materials with coordination bonds provides an effective, energy-saving, and green method, which is expected to promote the large-scale and fine production of electrochromic materials.
