| Recently, semiconductor nanocrystals have been extensively studied because of their unique size dependent electronic, optical, and electrochemical properties. It is known that these properties depend on a number of factors including the nature of the stabilizing ligand. In this regard, we have designed a series of conjugated oligofluorene surfactants that can be attached directly as stabilizers for CdSe or CdS nanocrystals. The electronic interactions of the nanocrystal/oligofluorene complex will be studied with respect to the conjugation length of the ligand. We will explore two routes for the fabrication of these nanocrystal/oligofluorene complexes including a “grafting to” and a “grafting from” approach. Using a “grafting from” approach, nanocrystals will be passivated with functional, conjugated surfactants and used as synthetic reagents in order to facilitate the design of conjugated oligomers and polymers grown from the nanoparticle surface. |
