Two chiral (A) 6 B‐typed supramolecular cages were constructed from hydrogen‐bonded C 6 ‐symmetric zinc porphyrin hexamers and chiral C 3 ‐symmetric pyridyl hexadentates with a core of 1,3,5‐triphenylbenzene. Circular dichroism and molecular simulations revealed that the symmetry of the supramolecular cages switched from pseudo‐ C 3 v to C 3 with the rotational confinement of the biphenyl backbones at low temperatures, which generated conformationally chiral transfer and amplification. This unique phenomenon suggests a new strategy to develop smart materials with high sensitivity and excellent reversibility.
