Synthesis and photophysicochemical properties of novel mononuclear rhodium(III) phthalocyanines

摘要

Chloro axially-substituted octa(4-isopropylphenoxy)rhodium(III) phthalocyanine, (R)_8PcRhCl (3), was reacted with the nitrogenous bases pyridine (Py) and pyrazine (Pyz) to give the axially-disubstituted octa(4-isopropylphenoxy)rhodium(III)phthalocyanines [(R) _8PcRhCl(L)] (4) and (5), L = (Py) and (Pyz), respectively. In this study, the fluorescence quantum yield (ΦF), the phosphorescence quantum yield (Φphos) and the photodegradation quantum yield (Φpd) values for the newly synthesized rhodium phthalocyanine complexes (RhPcs) 4 and 5 are reported. The complexes have also been fully characterized by elemental analysis, FD mass spectrometry, FT-IR and 1H NMR spectroscopy.
