Discrete Actuation of Water-Responsive Crystalline Metal-Peptide Frameworks.

ABSTRACT: Engineering guest-responsive materials capable of controlled and precise sorption behavior and structural deformation in response to external stimuli is imperative for various applications. However, existing systems often exhibit complex, unpredictable dynamics, posing challenges for efficient control and utilization. Here, we design crystalline metal-peptide frameworks with tunable water-responsive (WR) dynamics by assembling glycine-threonine (Gly-Thr, GT) or glycine-serine (Gly-Ser, GS) peptides with zinc (Zn) ions, achieving either continuous or discrete threshold water-sorption-dependent phase transitions. As ambient relative humidity (RH) changes, the Zn-GT crystal continuously adsorbs or desorbs water, resulting in gradual structural adaptations, similar to those observed in other s
