Hi All,
I use commercial quantum dot from evident tech, and from the datasheet I can know its molecular weight (Mw), my question is, is this Mw also includes the organic ligand or only consider its core? what is the normal case?
thanks,
Yuliar
Hi chemisttree, thanks for your sharing. Thats exactly I try to avoid, to be hated by my colleagues in the lab..:), I will be more cautious to use this substance then..
Hi,
Just simple question, how dangerous is 1,4 benzenedithiol? Does it have a strongly disagreeable odor like some of the thiol molecules? And what kind of handling of this material needs to be done?

Ah yes, Sorry, I should be more specific. The solvent used are the non-polar one such as Toluene and chlorobenzene. I will need it for solar cell application whereas normally the new ligand needed are the short one which allow efficient charge transfer and at the same time give stability of the...
Hi everyone,
I'm working with quantum dot (PbS). However, I'm actually not a chemist, so could anyone help me to address some issues regarding quantum dots especially related to ligand exchange process. My questions are:
1. anyone can address about what kind of functionality (e.g: thiol...
thanks for your reply. I thought the same think too after posted this thread. It must be related to the increase of a net positive charge (from the atomic nucleus contribution), so the coulomb attraction between the next negative charge and positive charges is increasing. The implication is the...
Hi,
I just read a paper about charge transport in organic semiconductor. There, it was mention that from electrochemical experiments, it is well known that after the removal of one electron from an individual molecule, more energy is required to remove a second electron. I'm still confuse...
