Non-linear optothermal properties of metal-free phthalocyanine

Synthesis, electrochemistry of metal-free, copper, titanium phthalocyanines and investigation of catalytic activity of cobalt, iron phthalocyanines on benzyl alcohol oxidation bearing 4-{2-[3-trifluoromethyl)phenoxy]ethoxy} groups

“…Synthesis 2.1.1. Synthesis of metal-free phthalocyanine (2) 4-{2-[3-Trifluoromethyl)phenoxy]ethoxy}phthalonitrile 1 (0.2 g, 0.60 mmol), 1.8-diazabicyclo [5.4.0]undec-7-ene (DBU) (4 drops) and dry n-pentanol (3.5 ml) was added in a Schlenk tube and then was heated and stirred at 160 C for 24 h under N 2 gas atmosphere. After cooling to room temperature the reaction mixture refluxed with ethanol to precipitate the product which was filtered off.…”

“…The synthesis and subsequent study of a large number of phthalocyanines have presented due to their high potential applications in several areas for example optical devices [2], chemical sensors [3], semi-conductors [4], liquid crystals [5], catalysts [6], non-linear optics [7], Langmuir-Blodgett films [8], photovoltaic solar cells [9], gas sensors [10] and photodynamic therapy (PDT) which is new introduced method for treatment of the cancer cells [11][12][13]. The implementations of the most Pc compounds are restricted because of their poor solubility in common organic solvents and water.…”

“…In addition, electrochemical properties were investigated of the newly synthesized Pcs containing peripherally flouro functional groups for compound (2)(3)(4) and also examined their catalytic activity on benzyl alcohol oxidation for compounds (5,6).…”

Novel pthalocyanines bearing 4-ferrocenylphenoxy substituents and their electrochemistry

“…After cooling to room temperature the green crude product was precipitated with ethanol and then dried in vacuo. Furthermore this product was purified with column chromatography using (aluminium oxide) CHCl 3 3. Results and discussion…”

“…These properties make them suitable for a wide range of applications such as chemical sensors [1,2], nonlinear optical devices [3], optoelectronics [4,5], liquid crystal [6,7], semiconductors [8], solar cell [9,10], gas sensors [11], photodynamic therapy [12e14]. However, the use of phthalocyanines in these areas is limited by their low solubility in common organic solvents.…”
