Abstract

We report direct photopatterning and erasing of colloidal quantum dots (QDs) via a ligand photoisomerization mechanism. Unlike previous approaches involving bond formation or breaking, the reversible ligand isomerization under UV and visible light modulates colloidal solubility, enabling high-fidelity writing and “on-demand” erasure of QD patterns while maintaining their luminescent properties.
