摘      要：Metal-organic frameworks(MOFs)have attracted significant attention in the past two decades due to their diverse physical properties and associated *** numerous advances have been made,the acoustic properties of MOFs have attracted very little ***,we systematically investigate the acoustic velocities and impedances of 19 prototypical MOFs via first-principle *** results demonstrate that these MOFs exhibit a wider range of acoustic velocities,higher anisotropy,and lower acoustic impedances than their inorganic counterparts,which are ascribed to their structural diversity and anisotropy,as well as low *** addition,the piezoelectric properties,which are intimately related to the acoustic properties,were calculated for 3 MOFs via density functional perturbation theory,which reveals that MOFs can exhibit significant piezoelectricity due to the ionic *** work provides a comprehensive study of the fundamental acoustic properties of MOFs,which could stimulate further interest in this new exciting field.
