Correlation dependences in infrared spectra of metal phthalocyanines

Synthesis and Isolation of 2,9,17,23-Tetrakis[(3,5-dimethyl-1H-pyrazol-1-yl)phenoxy]phthalocyanine and Its Magnesium(II) and Zinc(II) Complexes

“…For all phthalocyanines 2-4 the characteristic bands of stretching vibrations of C Ar -H and C alk -H fragments of relatively low intensity appear in the range of 3100-2800 cm In the IR spectra of phthalocyanines 2-4 new bands corresponding to the stretching vibrations of C-N bonds of pyrrole fragments in phthalocyanine core [50] appear at 1338 and 1335 cm -1 for 2 and 3, 4, respectively. The intensive band of stretching vibrations of C Ar -O-C Ar groups at 1251 cm -1 for phthalonitrile 1 is shifted to low frequency area and became broad band at 1234, 1231 and 1232 cm -1 for 2, 3, and 4, respectively.…”

“…The bands of phthalonitrile 1 at 854, 832, and 821 cm -1 appear as broad single bands at 834 and 833 cm -1 for phthalocyanines 2 and 3, 4, respectively. Also, bands of bending vibrations of phthalocyanine core [50] appear at 747, 753 and 748 cm -1 for phthalocyanines 2, 3, and 4, respectively.…”

“…At the same time, the band of bending vibrations of C Ar -O-C Ar groups at 1094 cm -1 for 1 is slightly shifted to 1092, 1081, and 1089 cm -1 for phthalocyanines 2, 3, and 4, respectively. The bands of totally symmetric bending vibrations of isoindole fragments of phthalocyanines [50] appear at 1113, 1114, and 1116 cm characteristic intensive bands of plane bending vibrations of C Ar -H bonds in phthalocyanines appear at 1037, 1044, and 1043 cm -1 for phthalocyanines 2, 3, and 4, respectively. The low intensity band at 1009 cm -1 of phthalocyanine 2 is caused by bending vibrations of N-H bonds.…”

Synthesis and Photophysical Properties of Phthalocyanines with 4-(1-Methyl-1-phenylethyl)phenoxy Groups

“…In the IR spectra of phthalonitriles (4-6) the stretching vibration of C≡N at 2230-2240 cm -1 , the vibrations of methyl and methylene groups of 4-(1-methyl-1-phenylethyl)phenoxy groups at 2950-2830 cm -1 , as well as symmetric (1340-1385 cm -1 ) and asymmetric (1525-1565 cm -1 ) vibrations of the NO 2 group [18,19] of compound 4 are observed.…”

Adsorption of Zinc Phthalocyanine on Carbon Materials

“…Полученные результаты соотносились с ИК-спектром чистого ZnPc (Рисунок 4) на основании аналогичных ли-тературных данных для металлокомплексов Pc. [14] Для адсорбированного на поверхности графи-та ZnPc в разностном спектре (Рисунок 4а) наблю-дается сдвиг практически всех полос, характерных для ИК-спектра чистого ZnPc (Рисунок 4б), преимуще-ственно в область больших волновых чисел. Происхо-дит также расщепление полос поглощения, связанное, вероятно, с низкими значениями ΔD.…”
