A single-wavelength dual-emissive polymeric probe shows fluorescence enhancement toward ClO ⁻ and phosphorescence quenching toward O ₂ , allowing simultaneously imaging cellular ClO ⁻ and O ₂ via time-resolved photoluminescence imaging microscopy.

Rhenium(i) complexes modified with a tetrazine carbamate group were designed as bioorthogonally dissociative photosensitisers for the controlled induction of immunogenic cell death (ICD) after treatment with trans-cyclooct-4-enol and light.
