Abstract

The invention discloses a class of thienyl chalcogen-containing viologens and biquinoline derivatives and applications thereof, belonging to the field of electrochromic devices and energy-saving displays. The thienyl chalcogen-containing viologen and its biquinoline derivatives have more stable free radical state; narrower band gap width, stronger visible light absorption; lower reduction potential and very low LUMO energy level. In addition, such compounds also have stable free radical states with different colors, making them more effective in static / dynamic electrochromic displays. The successfully synthesized thienyl chalcogen-containing viologen or thienyl chalcogen-containing biquinoline derivatives successfully synthesized in the present invention are widely used in photochromic devices and electrochromic devices, such as visible photochromic devices, mobile phone remote control electronics, etc. Electrochromic devices and mobile phone remote control flexible electrochromic devices, electronic tablet, electronic digital display / price tag, multi-color pixel electrochromic display and double-encrypted electrochromic display, etc.

Description

technical field

[0001] The invention belongs to the field of electrochromic devices and energy-saving displays, and relates to a class of thienyl chalcogen-containing viologens and their biquinoline derivatives and applications. Background technique

[0002] Currently the most popular OLED display technology has high power and high energy consumption due to its active light emission, and its stability and lifespan need to be further improved during the period. The electrochromic display technology has a very attractive application prospect due to its wide-range adjustable light transmittance, diverse and continuous color changes, and the advantages of storage and memory functions, low driving voltage, and energy saving. Such materials can not only be used as large-scale architectural decoration materials and optical materials, such as smart windows, anti-glare rearview mirrors, color-changing sunglasses, etc., but also can be used in display technology, including color elect...
