Photocurrent generation from a low band-gap and green BODIPY-based electrochromic polymer

- The electrosynthesis of a low band-gap and neutral-state green BODIPY-based polymer has been described.
- The resulting polymer exhibits two well-defined absorption bands at 430 and 690 nm, allowing it to absorb light across the visible spectrum.
- The resulting polymer shows electrochromic behavior wherein the color changes from neutral-state green to oxidized-state dark blue.
- The electrogenerated thin film of the polymer displays high out-of-plane hole mobility in solid state.
- The freestanding film of the resulting polymer registers a photo-electrochemical response when light is applied.
