Looking for a low boiling point solvent for MAPI precursors

Click For Summary
SUMMARY

The discussion focuses on finding low boiling point solvents for MAPI precursors, specifically exploring Acetonitrile (ACN) with HI and DMSO additives. The challenge with HI is its 55% aqueous solution, which is incompatible with perovskite materials. The potential use of DMSO is uncertain as it may significantly raise the boiling point. Additionally, methyl isopropyl ketone is mentioned as a possible solvent for PbI2 with a boiling point of 92°C, although its solubility properties may vary.

PREREQUISITES
  • Understanding of MAPI (methylammonium lead iodide) chemistry
  • Knowledge of solvent properties and boiling points
  • Familiarity with additives like HI (hydroiodic acid) and DMSO (dimethyl sulfoxide)
  • Basic grasp of perovskite material compatibility
NEXT STEPS
  • Research the solubility properties of methyl isopropyl ketone for MAPI precursors
  • Investigate the effects of DMSO concentration on boiling point and solubility
  • Explore alternative solvents for MAPI, focusing on low boiling point options
  • Examine literature on ACN/Methylamine mixtures for MAPI applications
USEFUL FOR

Chemists, materials scientists, and researchers working on perovskite solar cells or related applications will benefit from this discussion.

Things I have thought of till now:

  1. Acetonitrile with HI additive
  2. Acetonitrile with DMSO additive
The problem with the first would be that HI is in an around 55% aqueous solution and water doesn't play well with the perovskite. Meanwhile, the second might end up needing enough DMSO to drastically increase the boiling point. I am not sure about the second and intend to try it out and will post updates when I am done. The only thing I have been able to find in the literature was ACN/Methylamine and I don't really have the apparatus at the moment for that.
 
Chemistry news on Phys.org
MAPI = methylammonium lead iodide.
I don't have a great answer for you, but defining less common acronyms might make it easier to find someone who does. Unless you're adding a ton of DMSO, I can't imagine it would increase your boiling point that much. Wikipedia says methyl isopropyl ketone for PbI2 (bp=92°C). It has a reasonable shot at dissolving methylammonium iodide as well, but wiki can be way off with things like solubility properties.
