Abstract
Novel tris(salen)-type trinickel(II) metallocryptands, [LNi3] (L = L1, L2), were designed and synthesized. The metallocryptand [L2Ni3] perfectly encapsulated a guanidinium ion in the cavity. The resulting guanidinium complex underwent significantly slow helix inversion compared to the free [L2Ni3]; thus the helix inversion rate was efficiently regulated by guanidinium recognition.
