Abstract
Ligand-capped inorganic particles, dispersions of the ligand-capped inorganic particles, and films composed of the ligand-capped inorganic particles are provided. Also provided are methods of patterning the films and electronic, photonic, and optoelectronic devices that incorporate the films. The ligands include bifunctional ligands and two-component ligand systems that include a photosensitive group, cation, or molecule.
