Looking for a low boiling point solvent for MAPI precursors

[Enigman]

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.

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.
