Scheme S1. Mechanism for HID photoproduct formation during photolysis pyrophthalone doped polycarbonate films.
Scheme S2. Plausible photodegradation product structures that could be assigned for the second major photoproduct with M.wt. 228 [M+1].
Figure S1. LC-MS showing two major degradation photoproducts in the polycarbonate films.
Figure S2. Mass analysis of two major degradation photoproducts in the polycarbonate films one photoproduct with M.wt 163 was assigned to the formation of triprotonated 1H-indene-1,2,3-trione and the structure of M.wt 228 could not be elucidated.
