Abstract:The hydrogen bonds between the hydrogen of pyrrols in 5-(2-carboxyphenyl)-10,15,20-triphenylporphyrin and the oxygen of the carboxyl group of amino acid ester were confirmed by UV-Vis spectroscopic titration method and 1H-NMR. When amino acid ester was added to o-TPPCO2H solution in CHCl3, the Soret and Q and red-shifted dramatically and several isobestic points could be observed in UV-Vis spectra. In 1H-NMR, the signal of the hydrogen atoms of pyrrole in o-TPPCO2H (-2.78 ppm) decreased and a new signal in 0.260 ppm emerged, when o-TPPCO2H mixed with L-PheOEt at 1 : 1 (mol/mol).
