Thus, the triradical thin films are much less robust in the air, as expected, given the results already obtained for diradicals. Drop-cast films change on a longer time scale if exposed to air. These changes are different and might be due to structural changes. Additionally, because the drop cast films are thicker by two orders of magnitude than the evaporated films (nm versus hundreds of nm), I speculate that the changes in intensities originate also from the degradation of the more superficial layers of the drop cast films. These degraded layers then act as a protective buffer for the underneath material that keeps its properties.
