Synthesis, characterization and photodynamic activity of a new amphiphilic zinc phthalocyanine

Synthesis, electrochemistry and in situ spectroelectrochemistry of novel hexadeca-substituted phthalocyanines with three different groups

“…Spectroscopic properties of the phthalocyanines also depend on the positions of the substituents. When electron-donating substituents are bound to nonperipheral positions of the phthalocyanine skeleton the Q-band shifts further to longer wavelength than substitution at peripheral position [19][20][21][22]. It is well known that having an axial substituent on the metal center of the phthalocyanine also displays a bathochromic shift of the Q-band absorption maxima [23].…”

Water soluble quarternizable gallium and indium phthalocyanines bearing quinoline 5-sulfonic acid: Synthesis, aggregation, photophysical and electrochemical studies

“…In recent years, many efforts to make the best specified molecular materials aredevoted on chemical sensors [4][5][6], semiconductors [7], electrochromic display devices [8][9][10], liquid crystals [11,12], solar cells [13], photovoltaics [14] various catalytic processes [15,16] and photosensitizers [17,18]. Phthalocyanines well known to possess the photosensitizer activity are commonly used in PDT (photodynamic cancer therapy) because of their absorptions inthe red region [19].…”

Nonperipheral tetra phthalocyanines bearing alkyl chain moiety; Synthesis, characterization and fabrication of the OFET based on phthalocyanine

“…In recent years, Phthalocyanines are studied as well-defined molecular in high technological area such as, chemical sensors [3][4][5], semiconductors [6], electrochromic display devices [7][8][9], liquid crystals [10,11], solar cells [12], photovoltaics [13], various catalytic processes [14,15], and photosensitizers for photodynamic cancer therapy [16,17]. Because of the extended p-system, phthalocyanine compounds exhibit a tendency in solution to form the dimer and higher oligomeric species therefore, many phthalocyanines have been restricted in application areas owing to their lower solubility in common organic solvents due to aggregation.…”
