In summary, we report on an exceptional structural framework enabling reversible and bistable all-red-light responsive photoswitching. The PAT photoswitch offers highly efficient photoisomerizations with NIR and 617/590 nm light and high thermal stability of the metastable state leading to very strong isomer accumulations in the pss and predictable structural changes upon switching. A first application for red-light responsive photochromic polymers that undergo pronounced color contrast changes from green to blue is also delivered showcasing the proficient utility of the PAT photoswitch for smart materials. PATs strongly red-shifted absorptions thus push the limit of low energy light addressability of molecular photoswitches and will be instrumental for a next generation of photoresponsive molecular enablers in all application areas of chemical research.
