Abstract

The present inventions relate to optical components which include quantum confined semiconductor nanoparticles, wherein at least a portion of the nanoparticles include a ligand attached to a surface thereof, the ligand being represented by the formula X-Sp-Z, wherein: X represents: a primary amine group, a secondary amine group, a urea, a thiourea, an imidizole group, an amide group, a carboxylic acid or carboxylate group, a phosphonic or arsonic acid group, a phosphoric acid group, a phosphate group, a phosphite group, a phosphinic acid group, a phosphinate group, a phosphine oxide group, a phosphinite group, a phosphine group, an arsenic acid group, an arsenate group, an arsenous acid group, an arsenite group, an arsinic acid group, an arsine oxide group, or an arsine group; Sp represents a group capable of allowing a transfer of charge or an insulating group; and Z represents a multifunctional group including three or more functional groups capable of communicating a specific property or chemical reactivity to the nanoparticle, wherein at least three of the functional groups are chemically distinct, and wherein Z is not reactive upon exposure to light.
