A key element in designing photosensitizers is the ability to predict
the molecular structures that will trap the energy of photons and convert it
into cancer-destroying activity. We use time-resolved spectroscopic techniques
to study these properties systematically. By examining the emissive and
non-emissive excited states of our compounds, we can elucidate the electronic
structures of the compounds in our library, and describe the pathways available
to a molecule after it has absorbed a photon.
