N2 - Three new cadmium(II)-containing tripyrroledimethine-derived, 'texaphyrin'-type, macrocycles are discussed. These compounds, which contain extended π-systems, possess strong, low-energy, Q-like absorption bands in the 650-900 nm spectral region, making them of possible interest in photodynamic applications. Time-resolved absorption and emission laser studies have been carried out and the fluorescence and triplet absorption spectra, excited state yields and lifetimes, O2-quenching rate constants, and quantum yields for formation of O2(1Δg) measured and related to the structure of the macrocycle. The results of preliminary cell localization and in vitro photodynamic anti-viral, anti-bacterial, and anti-leukemic cell inactivation studies carried out with these and/or the parent o-phenylenediamine-derived parent texaphyrin system, are also presented.
