The FT-IR spectrum of TCuPh is given inFig. 2. It has characteristic peaks at 3037 and 2912 cm
1 for aromatic C- H stretching, 1614 for C=C macrocycle ring deformation, 1504 cm 1 for C=N stretching, 1328 cm 1for C-C stretching in isoindole, 1093 cm 1 for CeH in plane deformation and at 738 cm 1 for C-H out of plane deformation of phenyl ring which differed from CuPh to some extent due to substitution. TCuPh also shows additional bands that do not exist in the CuPh spectrum due to its four amide groups bonded to peripheral benzenoid rings of the macrocycle. These peaks include N- H stretching bands at 3317 cm1and 3167 cm 1 ,C]O stretching of the amide at 1656 cm 1, and N-H bending combined with C=N stretching at 1583 cm1
