Semiconductors are at the heart of nearly all things computerised, and with nearly all things computerised that makes semiconductors important. Semiconducting nanocrystals have become an interesting area of research because as colloidal inks they can potentially be used to easily print onto substrates to create photo-voltaic devices or a broad range of electronic devices.
This Hot Communication from the Brutchey group details the use of a ligand which exchanges with the capping ligand of semiconducting CdSe nanocrystals making them highly dispersible in a range of polar solvents (in DMF a stable colloid forms for > 2 weeks). Under mild conditions thermolysis transforms the surface bound ligands to thiocyanate in situ, producing nanocrystal films of CdSe(SCN). There are also indications of improved inter-particle coupling…
