Water-soluble quantum dots obtained through ligand exchange are widely applicable for biological imaging and marking, LEDs, and photovoltaics. Lipoic acid (LA) was reduced to dihydrolipoic acid (DHLA) using 365-nm soft UV light in a process known as photoligation, and ligand exchange with dodecanethiol-capped CuInS₂-ZnS core-shell quantum dots occurred. The reaction...
