I am working on Antimony based perovskites..it is observed that SbI3 has very poor solubility in most organic solvents. So i always need to filter out the solution..Any suggestions to improve its solubility ?
I have tried adding HCl, it works...but i usually make the films in DMF...need some other additive to improve solubility..Probably dimethyl amine should work then.

On SbI3 solubility in non-aqueous solvents:
― Said to be soluble in: benzene, ethanol, acetone, carbon disulfide, diiodomethane, SnCl4. (*)
― Solubility in diiodomethane: 10.15% v/v (12 °C) (**).
― Insoluble in CHCl3, CCl4.(*)
― Soluble in boiling toluene.(***)
― Probably soluble in dioxane.(****)
