Photosensitizers

We offer a range of water-soluble organic photosensitizers for the efficient generation of singlet Oxygen, ¹O₂.  Our photosensitizers typically have high extinction coefficients, triplet states of appropriate energies (ET > 95 kJ mol-1) to allow for efficient energy transfer to ground state oxygen, a high triplet state yield with long triplet state lifetimes.  We offer several sensitizer products over the visible spectral range.

All our photosensitizers are sold dry and are simply reconstituted by adding water/MeOH/EtOH and/or buffer.  One vial of one of our sensitizer probe will typically allow for 10 measurements to be undertaken, when further diluted into 3 cm³ volumes within a cuvette.

For optimum performance, probe vials should be stored at -2 to -8 C when not being used.  Probe sensitizer solutions should be used after dilution.
