A novel, robust chemical method for the detection of singlet oxygen is reported. It uses the oxo-ene reaction of the largely available and inexpensive dicyclopentadiene which is transformed by singlet oxygen into a hydroperoxide, quantitatively converted in situ by acetic anhydride and pyridine into a stable ketone, easily detectable by standard GC. The method has been tested in the detection of singlet oxygen as generated by standard organic pigments used in commercially available tubes for fine art paintings.
