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).sub.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.

The present invention provides a method for industrially producing a highly pure aromatic nitrile compound and a highly pure aromatic carboxylic acid compound safely and highly efficiently at low costs. Compound (2) is subjected to Willgerodt reaction in the presence of an additive as necessary, and the obtained amide compound (3) is hydrolyzed and neutralized to give carboxylic acid compound (4). Carboxylic acid compound (4) is reacted with a halogenating agent in the presence of a catalyst as necessary in an organic solvent, and further reacted with an amidating agent, and the obtained amide compound (5) or (6) is reacted with a dehydrating agent to give nitrile compound (1). Alternatively, carboxylic acid compound (4) is reacted with a halogenating agent and a compound represented by the formula R.sup.6SO.sub.2R.sup.7 in the presence of a catalyst as necessary in an organic solvent to give nitrile compound (1). Np is a naphthyl group optionally having substituent(s), R.sup.5 is an alkylene group having 1-3 carbon atoms, and other symbols are as described in the DESCRIPTION.
