Absorption spectra and photosensitization of 1O2 by TBBPA in MeCN. A: 1O2 phosphorescence observed during the irradiation of TBBPA, 10mM, Spectrum S1; 1mM, S2, and saturated solution, S3. B: The corresponding absorption spectra, 1, 10mM, 2, 1mM, and 3, saturated solutions of TBBPA. The solutions were irradiated by a 300 Watt Hg lamp through water and interference (F) filters. Absorption increase observed during the irradiation of saturated TBBPA solution after 2 min., 3a; 7 min., 3b, and 17 min., 3c, of irradiation.
