Abstract
Chloro axially-substituted octa(4-isopropylphenoxy)rhodium(III)phthalocyanine, (R)(8)PcRhCl (3), was reacted with the nitrogenous bases pyridine (Py) and pyrazine (Pyz) to give the axially-disubstituted octa(4-isopropylphenoxy)rhodium(III)phthalocyanines [(R)(8)PcRhCl(L)] (4) and (5), L = (Py) and (Pyz), respectively. In this study, the fluorescence quantum yield (Phi(F)), the phosphorescence quantum yield (Phi(phos)) and the photodegradation quantum yield (Phi(pd)) 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 H-1 NMR spectroscopy. (C) 2011 Elsevier Ltd. All rights reserved.
