Dimethylformamide reached an average level of 28 ugL in the blood of subjects exposed to 21 ppm of the vapor for 4 hr and was undetectable at 4 hr after the exposure. By dilute nitric acid gives modest yields of nitrated phenols and considerable oxidative decomposition to tarry materials. For instance both DMF and DMSO will boil below 50 C if the vacuum is reduced from 760 torr.

We discovered that common solvents such as dimethyl sulfoxide DMSO and dimethylformamide DMF do not favor fast deposition of a compact and smooth perovskite film at room temperature while highly volatile solvents of 2-methoxyethanol 2-ME and acetonitrile ACN lead to perovskite films with low crystallinity and poor contact to the substrates. In this example care must be taken to maintain a low temperature.
