Solvent participation
When carrying out chemical reaction, the most important thing is the stoichiometric amount between starting material. Even if one reagent is in excess, it should not interfere with the reaction or solvent. But in many cases it does. Another crucial thing is choosing a suitable solvent. Avoid choosing nucleophilic solvent such as acetone in the reaction.
It’s best to choose volatile solvent so that you can easily vaporize that to get the crystal powder. Some good solvent (not the best) are ethanol, toluene or hexane.
For synthesis of quantum dots, common solvents are TOP/TOPO or Oleic Acid/Octadecene. Some people refer octadecene as non-coordinating solvent. I’m sure what does it mean. Perhaps octadecene does not contribute to ligand passivization.
