Figure 2

Absorption (–) and fluorescence emission (···) spectra of 2-TQP (red) and TPP (black) recorded at room temperature in tetrahydrofuran (THF) and deaerated toluene solutions, respectively. Absorbance was monitored from 350 to 750 nm and fluorescence emission upon excitation at 552 nm was monitored from 560 to 800 nm.
