General description

Reactive group: Carboxylic acid.

Application

The organic layer of the CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid as reactive group consist of a monolayer of oleic acid/octadecylamine and a monolayer of amphiphilic polymer. The total thickness of organic layers on these QDs is approximately 4 nm. They find many applications in bioimaging and biosensing.

Owing to their narrow bright emission band, broad size-tunable emission wavelength, superior photostability, and excellent flexible-substrate compatibility, light-emitting diodes based on quantum dots (QD-LEDs) are currently under intensive research and development for multiple consumer applications including flat-panel displays and flat
