General description

Tetradecylphosphonic acid forms a self-assembled monolayer (SAM) to functionalize a variety of nanoparticles.

Application

TDPA can be used to cap copper nanoparticles to protect them from oxidation. It may also be used in the synthesis of cadmium sulfate (CdS) core, which can be used in the fabrication of cadmium selenium (CdSe)/CdS core quantum dots (QDs). It may also be coated on caesium lead bromide (CsPbBr3) perovskite quantum dots for the development of white light emitting diodes (wLED).
