Abstract:
Photochromic polymers and aggregation-induced emission (AIE) materials show great potential for many applications. To explore the synergy of both characteristics in polymer material areas, we reported the first synthesis of tetraphenylethylene (TPE)-diarylethene (DAE) polymer and its application as a super-resolution probe for imaging self-assembled cylindrical micelles of PSt38k-b-PEO11k. The polymer exhibits high fluorescence ON/OFF ratios, visible-light-driven photocycloreversion, and AIE properties. Compared with other DAE materials studied in super-resolution imaging, our polymer shows advantages of visible-light-driven photocycloreversion, higher resolution, higher fluorescence quantum yield, or higher thermal stability.
