“…The calculated N-H stretching vibration in H 2 Pc at 3559 cm −1 in this work corresponds well with both the previous calculation results at 3561 cm −1 [59] and the experimental data at 3404 (3273/0.9614) cm −1 [60]. The calculated N-H stretching vibration in 5.1 at 3563 cm −1 in this work also agrees well with the corresponding N-H vibration in other peripherally tetrasubstituted metal-free phthalocyanines, with the alkoxyl-containing groups in the range of 3375-3428 cm −1 [49][50][51][52][53]. This agreement also holds for compound 6 [54,55].…”

“…This finding is also true for compound 5.2. The calculated absorption bands of 5.1 and 5.2 can also find analogs in the electronic absorption spectra of some other peripherally tetrasubstituted metal-free phthalocyanines with the alkoxyl-containing groups [49][50][51][52][53]. Novel metal-free phthalocyanines containing four 19-membered dithiadiazadioxa macrocycles show split Q bands at 707 and 689 nm and B bands at 334 and 281 nm [54], which correspond to the calculated electronic absorption bands of 6 at 612 and 600 nm and 329 and 292 nm, respectively.…”

“…The oxidation system was further examined by UV–visible spectroscopy during the processes in order to investigate the catalytic mechanism for the Co‐catalyzed cyclohexene oxidation. The spectra of cobalt(II) phthalocyanines has been the subject of several reports . The spectrum of metal–phthalocyanine (MPc) complexes is well known and consists of an intense band, called the Q band, in the visible region .…”

“…The implementations of the most Pc compounds are restricted because of their poor solubility in common organic solvents and water. Their solubility can be increased by attaching substituents such as long alkyl or alkoxy chain, macrocyclic, phenoxy groups to its peripheral or nonperipheral positions of the phthalocyanine rings [14][15][16][17][18].…”
