Quantification of singlet oxygen sensitized by HPPH and conjugates 2–7. The decays of the singlet oxygen phosphorescence at 1270 nm are shown on the left and the singlet oxygen yields obtained from the decays using HPPH as a reference21 are on the right. Absorbance of the samples (methanol solutions) was matched at the wavelength of excitation (532 nm).
