Researchers at Purdue University have developed novel azopolymers for electrochromic applications. These azopolymers might be intrinsically suitable as n-type materials due to the N=N pi* LUMO level being low-lying, which would offer new choices in device design. Additionally, these azoploymers are relatively less expensive than comparable materials. Applications may be electrochromic devices such as transition lenses and smart windows.

Advantages:
-Low-Cost
-High-Yield
-Efficient Synthesis

Potential Applications:
-Electrochromic Materials
-Transition Lenses
-Smart Windows

Technology Validation:
The chemical structure of the new azopolymers developed by Purdue researchers have been validated by x-ray crystallography and the percent yield for each of 13 unique polymers has been tested using proton and carbon nuclear magnetic resonance. In addition, cyclic voltammetry has been used to characterize the electroactivity of the new azopolymers.
