Abstract
The present disclosure relates to a nanocrystal that includes a nanocrystal core, a first ligand coordinated to a first portion of a surface of the nanocrystal core, and a second ligand coordinated to a second portion of the surface, where the second ligand includes a first functionalized aromatic molecule.
Claims15
A nanocrystal comprising:
- a nanocrystal core;
- a first ligand coordinated to a first portion of a surface of the nanocrystal core, and
- a second ligand coordinated to a second portion of the surface, wherein:
- the second ligand comprises a first functionalized aromatic molecule.

A method comprising:
- adding an exchange ligand to a first solution comprising a first solvent and a starting nanocrystal comprising a starting ligand coordinated to a surface of a nanocrystal core, wherein:
- the adding produces an exchanged nanocrystal in a second solution,
- the starting ligand and the exchange ligand have a ligand-ligand coupling energy less than −044 kBT, where kB is the Boltzmann constant and T is the temperature in Kelvin,
- 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 exchange ligand replaces at least a portion of the starting ligand coordinated to a portion of the surface, and
- the exchange ligand coordinates to the portion of the surface to produce the exchanged nanocrystal.
