The thermal decomposition of endoperoxides at higher temperatures leads to the production of O2. 2,7-dsDPA, 2,6-dsDPA and corresponding endoperoxides 2,7-dsDPAO2, 2,6-dsDPAO2 form 1:1 host–guest complexes with native cyclodextrins and 2-hydroxypropylated cyclodextrins. The binding constants depend on the cavity size and the functionalization of the primary face of CDs. The thermal stabilities of both endoperoxides in host–guest complexes with CDs and hpCDs are highly increased.
