Significance

A new type of poly(phenylene-co-fluorene) bearing diarylanthracene or diaryltetracene groups has been synthesized by Suzuki polymerization. The pendant linear acenes react with singlet oxygen (^¹O₂) via the [4+2] cycloaddition reaction to give endoperoxides. The resulting quenching of the acene fluorescence has been used to detect ^¹O₂, which is one of the most important reactive oxygen species.
