Abstract:
1. A semiconductor nanocrystal complex comprising: a surface-coated semiconductor nanocrystal comprising a semiconductor nanocrystal having a surface comprising molecules having a moiety with an affinity for the semiconductor nanocrystal and a moiety with an affinity for a hydrophobic solvent coating the semiconductor nanocrystal; and a diblock polymer coating surrounding the surface-coated semiconductor nanocrystal, the diblock polymer coating comprising a plurality of diblock polymers, each of the plurality of diblock polymers having a hydrophobic end for noncovalently interacting with the surface-coated semiconductor nanocrystal and a hydrophilic end, wherein adjacent ones of the plurality of diblock polymers are linked together by a bridging molecule.
