Targeting cancer cell mitochondria with a multivalent source of singlet oxygen [PDF]
Smart MoleculesNaphthalene, anthracene and pyridone endoperoxides are known to thermally release singlet oxygen. However, in the cycloreversion reaction, singlet oxygen is produced stoichiometrically; therefore, multiple singlet oxygen releasing modules are expected to
