This invention provides an electrochromic material, its preparation method, and its application. The structural formula of the electrochromic material is shown below: AR1 is a group represented by R1 or R3; AR2 is a group represented by R2 or R6; AR3 is selected from any one of R3, R4, and R5; AR4 is a group represented by R2; n is the degree of polymerization, and n is 4–35. This invention uses an arylation polycondensation process to prepare four high-performance solution-processable electrochromic materials: TTP, TEP, TPP, and PBP3P. Using these electrochromic materials as raw materials, high-performance patterned electrochromic camouflage devices are prepared using mask spraying. Nylon filter membranes with different pore sizes are introduced into the device structure to adjust the device's transmittance and achieve better camouflage effects.
