✦ Synopsis

The singlet oxygen quantum yield ('DA) for Photofrin@ solubilized by Triton X-100 was measured in homogeneous and lightscattering media using the photosensitized inactivation of lysozyme as an internal actinometer. Higher values of @* at 630 nm than at 514 nm are attributed to the formation of a far-red-absorbing photosensitizing photoproduct.
