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, an other nitrogen containing group, a carboxylic acid group, a phosphonic or arsonic acid group, a phosphinic or arsinic acid group, a phosphate or arsenate group, a phosphine or arsine oxide group; Sp represents a spacer group, such as a group capable of allowing a transfer of charge or an insulating group; and Z represents: (i) a reactive group capable of communicating specific chemical properties to the nanocrystal as well as provide specific chemical reactivity to the surface of the nanocrystal, and/or (ii) a group that is cyclic, halogenated, or polar a-protic. Compositions, systems, kits, films, inks, and TFEL lamps are also disclosed.
