Our  group has established the synthetic and analytic infrastructure required to develop a promising new class of materials that operate on the basis of their structurally programmed molecular motion.  With a combination of static elements and rapidly moving arrays, we refer to them as amphidynamic crystals.  Amphidynamic crystals can be built with discrete molecular units, supramolecular synthons, extended solids based on metal-organic frameworks, or other platforms. Among them, molecular rotors are expected to have functions that rely on units designed to rotate or reorient in response to external stimuli, such that they can display induced birefringence, dichroism, second-order non-linear optical responses, and other addressable physical properties.  With high order, structurally controlled degrees of freedom, and capable of responding to external stimuli in a predetermined manner, amphidynamic materials are a promising platform for the design of molecular machines.  This presentation will illustrate the development of these concepts with a particular emphasis on structures aimed at exploring emergent behavior that arises from dipolar interactions and architectures at the mesoscale.<br/>
