Even though the exact mechanism of evaporation for neither 1 nor 2 is known, it appeared manifest that the TMADS ligand in 2 impeded volatilization until a notable fraction of the analyte decomposed. Contrasting this, 1 apparently undergoes a conversion into a volatile and thermally stable product, presumably the monomer, upon heating. and co-workers still evidences the complexation approach to be viable for the synthesis of enhanced Co(II) ALD precursors. The most pronounced contrast in terms of thermal stability and volatility was observed for the two pyrrolato complexes 8 and 9 as it can be seen in (140 °C vs. 169 °C) but showed inferior thermal stability evidenced by a notably higher residual mass (21.6 % vs. 4.7 %). Dimeric compound 12 was subjected to TGA as well and the experimental data can be found in the SI. Unsurprisingly, the mass loss was found to be dominated by a multitude of overlapping decomposition events with no evidence for partial intact precursor evaporation which rendered 12 to be the least suitable CVD/ALD precursor candidate.
