Self-propelled
nanomotors represent a promising class
of adaptable
and versatile technologies with broad applications in the realms of
biomedicine and environmental remediation. Herein, we report a biocatalytic
nanomotor based on a covalent–organic framework (COF) that
demonstrates intelligent and switchable motion triggered by a blue-to-red
light switch. Consequently, when exposed to blue light, the nanomotor
significantly enhances the removal of contaminants in aqueous solutions
due to its elevated mobility. Conversely, it effectively deactivates
its motion and contaminant removal upon exposure to red light. This
study explores the heterogeneous assembly strategy of the COF-based
nanomotor and its light-controlled propulsion performance and provides
a novel strategy for the regulation of movement, offering valuable
insights for the design and practical applications of nanomotors.
