Here, we report a C3-symmetric tris-azobenzene cage 1 comprising azobenzene cores and bis(urea) units. This system demonstrates efficient reversible photoisomerization unprecedented anion-mediated switching modes. Specifically, the phosphate anion induces concerted ZZZ → EEE isomerization with prolonged thermal relaxation (t1/2 = 37.5 h at 298 K). In contrast, bulky benzene-1,3,5-tricarboxylate enforces stepwise pathway (ZZZ EZZ EEZ EEE) rapid 54.4, 44.5, 12.9 min for each step). study represents first demonstration of selective control over multi-azobenzene switch, mimicking biological adaptability through environmental changes.
