Question

This species can detoxify sulfur mustard in a zirconium (IV) MOF platform with pyrene linkers. The Jin and Tsien labs developed a genetically encoded tag called miniSOG for generating this species, which induces di·amino·benzidine polymerization for photodynamic therapy. This species can be trapped by reacting it with tetramethyl piperidone to form nitroxide radicals detectable by (-5[1])EPR. A (-5[1])xanthene-anthracene dyad called DMAX can sense this species by forming a bridged (*) peroxide via a classic four-plus-two cycloaddition. This species’s one-delta-g state converts to (10[1])its one-sigma-g-plus state to vacate a pi-star antibonding orbital. Methylene blue and Rose Bengal photosensitizers are used to produce this species, which is paramagnetic due to having (10[1])unpaired electrons. For 10 points, name this reactive oxygen (-5[2])species, the excited state of the (10[1])more common triplet (10[1])oxygen. (10[2]0[5])■END■

ANSWER: singlet oxygen [or dioxygen(singlet) or dioxidene; accept 1O2 or 1[O2]; prompt on oxygen, O2, diatomic oxygen, or dioxygen until “oxygen” is read; prompt on reactive oxygen species or ROS; reject “triplet oxygen”]
