Rational Design of Biological Crystals with Enhanced Physical Properties by Hydrogen Bonding Interactions.

ABSTRACT: Hydrogen bonds are non-covalent interactions and essential for assembling supermolecules into ordered structures in biological systems, endowing crystals with fascinating physical properties, and inspiring the construction of eco-friendly electromechanical devices. However, the interplay between hydrogen bonding and the physical properties is not fully understood at the molecular level. Herein, we demonstrate that the physical property of biological crystals with double-layer structures could be enhanced by rationally controlling hydrogen bonding interactions between amino and carboxyl groups. Different hydrogen bonding interactions result in various thermal, mechanical, electronic, and piezoelectric properties. In particular, the weak interaction between O and H atoms contributes to low m
