The supramolecular self-assembly of porphyrin-fluorescein hybrid (Fl-PPTPP) with copper(II) complexes of 5-(P-amino-phenyl)-10,15,20-triphenylporphyrin (p-APTPP), Cu-(11)(p-APTPP), by carboxyl-amino type hydrogen-bonding was studied using ESMS, UV-Vis spectra and fluorescence spectroscopic titration. A novel fluorescence strengthening character was observed in a fluorescence spectroscopic titration experiment for Fl-PPTPP/Cu-(11)(p-APTPP) system and the formation constant of (Fl-PPTPP)Cu-(11)(p-APTPP) supramolecular complex was determined from the fluorescence spectroscopic titration data.
