Abstract

To protect plants from photodamage under high light condition, photosynthetic system could switch from light-harvesting to photoprotective state. In this study, a supramolecular aggregate with lifetime of 9.29 μs and switchable photosynthetic activity was constructed. The efficient phosphorescence resonance energy transfer (PRET) process depended on the induced aggregate behavior between negatively charged diarylethene derivative and positively charged assembly. The photoprotective process was achieved through the photochromism of diarylethene derivative to quench excited state energy. Furthermore, the supramolecular aggregate also displayed low toxic and targeted mitochondrion ability.
