摘要
The present disclosure provides quantum dot organic ligand and preparation method thereof, quantum dot structure material, quantum-dot-containing layer, and quantum-dot-containing light emitting diode. The quantum dot organic ligand have the following structure R1-(R2)n-R3, wherein R1 is a chelating group capable of chelating with a metal; R2 is a group having a conjugated electron pair, and n is a positive integer; and R3 is organic group. The conjugated electron pair structure of R2 facilitates delocalization of electrons, which can improve the transport and conduction of electrons and/or holes, thereby improving the efficiency of quantum dots and lowering the turn-on voltage.
