Abstract

In this communication we report the preliminary results of in-situ functionalisation, of Q-CdSe and Q-GaAs using thiols, (HSC12H25), dithiols, (HSC9H18SH), pyridine derivatives (4-ethylpyridine, 4-butylpyridine) and carboxylic acids (mercaptopropionic acid).

The functionalisation of the capping group provides a potential route to the assembly of 2D arrays and supperlattices. Anchorage of the nanocrystals to surfaces for use in devices, such as solar cells and Grätzel type cells is also discussed.
