This research project from the University of Colorado and Northwestern University focuses on the innovative synthesis and characterization of surface-mounted molecular rotors. The study encompasses the design of rotor molecules with specified functions, exploring their electronic, optical, and fluidic dynamics. Key goals include developing low-friction surfaces, molecular machinery, and new optical materials. Additional achievements involve synthesizing new chemical structures and studying dielectric responses. Overall, this work aims to enhance applications in molecular motors and advanced transducer technologies.
