摘      要：Hydrogen-bonded molecules and their dynamics are significantly important in chemistry and biology due to their widespread *** their natural abundance and diversity,applications of molecules with dynamic conformations in artificial networks allow information storage and molecular motor design on the nanometer ***,we report hydrogen-bonded molecular networks with tunable helical conformation on metal *** dynamics of helical conformation in two-dimensional hydrogenbond networks are triggered and resolved by scanning probe microscopy at the single-molecule *** combinationwith theoretical calculations,the surfacespecific hydrogen bonds are identified as the origin of the dynamic helical *** results provide a distinctive access to molecular architecture with tunable helical conformation driven by hydrogenbond interaction on surfaces.
