Figure shows the respective TG graphs divided into three groups, a) DMP-stabilized alanes, b) amine stabilized and c) diamine stabilized alanes. Onsets of volatilization (Tvol.) were determined via 1 % mass loss and are summarized in the supplementary information, in table_SI 3. All compounds show single step evaporation, except 9, which shows decomposition at below 100 °C. This is in good accordance with decomposition over longer storage times (~1 week) even at -30 °C, where the compound forms a "solid foam" (figure_SI 2), most likely attributable to hydride elimination of the adjacent Al-hydride and amine-hydrogen. While such decomposition of compound 9 at room temperature and slightly above does not favor it as a CVD/ALD precursor, the intended concept of targeted decomposition via hydrogen elimination can be validated.
