  - 'We report a family of Pt and Pd benzoporphyrin dyes with versatile photophysical
    properties and easy access from cheap and abundant chemicals. Attaching 4 or 8
    alkylsulfone groups onto a meso-tetraphenyltetrabenzoporphyrin (TPTBP) macrocylcle
    renders the dyes highly soluble in organic solvents, photostable, and electron-deficient
    with the redox potential raised up to 0.65 V versus the parent porphyrin. The
    new dyes intensively absorb in the blue (Soret band, 440–480 nm) and in the red
    (Q-band, 620–650 nm) parts of the electromagnetic spectrum and show bright phosphorescence
    at room-temperature in the NIR with quantum yields up to 30% in solution. The
    small singlet–triplet energy gap yields unusually efficient thermally activated
    delayed fluorescence (TADF) at elevated temperatures in solution and in polymeric
    matrices with quantum yields as high as 27% at 120 °C, which is remarkable for
    benzoporphyrins. Apart from oxygen sensing, these properties enable unprecedented
    simultaneous, self-referenced oxygen and temperature sensing with a single indicator
    dye: whereas oxygen can be determined either via the decay time of phosphorescence
    or TADF, the temperature is accessed via the ratio of the two emissions. Moreover,
    the dyes are efficient sensitizers for triplet–triplet annihilation (TTA)-based
    upconversion making possible longer sensitization wavelength than the conventional
    benzoporphyrin complexes. The Pt-octa-sulfone dye also features interesting semireversible
    transformation in basic media, which generates new NIR absorbing species.@eng'
