Abstract
An aspect of the present disclosure is a nanocrystal that includes a nanocrystal core and a ligand coordinated to a surface of the nanocrystal core, where the ligand includes a functionalized aromatic molecule. In some embodiments of the present disclosure, the functionalized aromatic molecule may include at least one of cinnamic acid (CAH) and/or a functionalized CAH molecule.
Claims20
A nanocrystal comprising:
- a nanocrystal core;
- and
- a ligand coordinated to a surface of the nanocrystal core, wherein:
- the ligand comprises a functionalized aromatic molecule.
1 more element
A mixture comprising:
- a nanocrystal comprising a nanocrystal core and a ligand;
- and
- a solvent, wherein:
- the ligand is coordinated to a surface of the nanocrystal core, and
- the solvent, the nanocrystal, and the ligand form at least one of a stable solution-phase colloid or a stable ink.
2 more elements
A method comprising:
- adding an exchange ligand to a solution comprising a first solvent, a nanocrystal core, and a starting ligand, wherein:
- the exchange ligand comprises a functionalized aromatic molecule,
- the nanocrystal core comprises at least one of a Group II element, a Group III element, a Group IV element, a Group V element, Group VI element, or a noble metal,
- the starting ligand is coordinated to a surface of the nanocrystal core to form a starting nanocrystal,
- the exchange ligand replaces at least a portion of the starting ligand coordinated to the surface, and
- the exchange ligand coordinates to the surface to produce a ligand-exchanged nanocrystal in the solution.
