Spectroscopic and nonlinear optical properties of alkyl thio substituted binuclear phthalocyanines

Electrocatalytic behavior of single walled carbon nanotubes with alkylthio-substituted cobalt binuclear phthalocyanines towards oxidation of 4-chlorophenols

“…cm was obtained from Milli-Q Water Systems (Millipore Corp., Bedford, MA, USA). The synthesis and characterization of cobalt 4-b-pentylthio phthalocyanine (CoPc1), cobalt 4-b-pentylthio binuclear phthalocyanine (CoBiPc1), cobalt 4,5-b-pentylthio phthalocyanine (CoPc2) and cobalt 4,5-b-pentylthio binu clear phthalocyanine (CoBiPc2) have been recently reported in the literature [31] (see Fig. 1).…”

“…The cobalt complexes, cobalt 4-b-pentylthio phthalocyanine (CoPc1), cobalt 4-b-pentylthio binuclear phthalocyanine (CoBiPc1), cobalt 4,5-b-pentylthio phthalo cy -anine (CoPc2) and cobalt 4,5-b-pentylthio binuclear phthalocyanine (CoBiPc2), have been synthesized and previously reported [31]. The sulfanyl substituents on the complexes are stable enough not to undergo oxidation to form sulfonyl.…”

“…MPc-modified electrodes showed less effect of the polymerization of chlorophenols compared to bare glassy carbon electrodes [30]. This was attributed to the high porosity of the polymerized MPc layer, which allowed the passage of chlorophenol molecules to the polymer film [31]. Thus, the aim of this work is to reduce fouling by using a combination of SWCNTs and cobalt binuclear complexes (CoBiPc).…”

Zinc Phthalocyanine Thin Film-Based Optical Waveguide H2S Gas Sensor

“…Phthalocyanines (Pcs), especially metal Pcs show high photo-and thermal stability due to their 18-π conjugated electron system composed of carbon-nitrogen conjugated double bonds. As a class of macrocyclic planar aromatic compounds, MPcs are promising organic compounds with a huge potential for the application in electro-optical devices [19], photodynamic therapy [20,21], catalysts [22], nonlinear optics [23], and gas sensors [24][25][26].…”
