Photophysical, photochemical and aggregation behavior of novel peripherally tetra-substituted phthalocyanine derivatives

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

“…These properties make them important candidates as potential agents for fluorescence imaging and photodynamic therapy of cancer. [12][13][14][15][16] Unsubstituted phthalocyanines are known to have low solubility in most organic solvents that restricts of their application. Introduction of aryl or heteroaryl substituents in phthalocyanine core enhances solubility of macroheterocycles in many organic solvents and gives them new functional properties.…”

Characteristic absorption band split of symmetrically tetra-octyloxy metal phthalocyanines

“…non-coordinated solvents were concluded to be assembled into J-dimers by coordination between the center metal and the linker atom such as oxygen, sulfur and nitrogen [19][20][21][22][23][24][25][26][27][28][29][30][31]. However, they were not fully proven, i.e., it was very insufficient in credible characterizations, e.g.…”

“…However, they were not fully proven, i.e., it was very insufficient in credible characterizations, e.g. MS and 1 H NMR [19][20][21][22][23][24], or out of proportion for the weak dimer MS speaks to the strong Q absorption band split peaks [25][26][27][28][29][30][31]. Fig.…”

Photophysical and Photochemical Properties and Aggregation Behavior of Phthalocyanine and Naphthalocyanine Derivatives

“…strong π-π electron interactions, coulombic forces, central metal, position and size of the substituents, axial substituents on the central metal, temperature and solvent. 10,11 However, detailed studies comparing Pc and Nc aggregation in solution are lacking. 12,13 In the current study, we investigate the impact of the extended π-conjugation in macrocycles with same peripheral substituents ( Figure 1).…”
