Excited-state dimer formation followed by fluorescence. Titration of TM5Pyr in DMPC vesicles upon excitation at 345 nm: 2.56 μM (dashed line), 8.45 μM (solid line), and 10.2 μM (dotted line). For ease of comparison, intensities of the spectra are normalized to the 380 nm peak of the pyrene monomer.
