What kind of bonds it formed between quantum dots and their ligands? Are they hydrogen bond?

I want to modify PEI as the surface ligands to substitute OA/OAm on copper sulfide nanocrystals, however i do not know in which way to modify PEI.

Does anyone could tell me the mechanism of ligands attaching on quantum dots? How does people choose chemicals as ligands?
