“…The higher sensitivity of the hybrid film to benzo[a]pyrene is apparently due to the large number of adsorption sites available for the analyte molecules on the surface of the SWCNT/CuPc2g layer, which is associated with a large surface area-to-volume ratio compared with the CuPc2g film. A similar increase in the sensor response of hybrid layers compared to pure phthalocyanine films was also observed when investigating the TIRE sensors toward pesticides (pentachlorophenol (PCP), 2-chlorophenol (2CP), diuron, and simazine) in water [92,93]. The hybrids were prepared by non-covalent functionalization of acid-treated SWCNT with CuPc1l bearing R = −S(CH2)15CH3.…”

In this review, the state of research over the past fifteen years in the field of the applications of metal phthalocyanines and porphyrin derivatives as well as their hybrid materials with carbon nanotubes, metal oxides, and polymers in optical sensors based on the phenomenon of surface plasmon resonance (SPR) is analyzed. The first chapter of the review presents an analysis of works on the use of porphyrins and phthalocyanines in classical SPR sensors for the detection of gases and volatile organic vapors, as well as their improved modifications, such as total internal reflection ellipsometry (TIRE) and magneto-optical SPR (MOSPR) methods, while the second chapter is devoted to their application for the detection of various analytes in solutions. The third chapter of the review summarizes publications describing recent advances in the use of porous materials based on hybrids of carbon nanotubes and oxides with metal phthalocyanines. The fourth chapter describes two-dimensional metal-organic frameworks (MOFs) based on metal porphyrin derivatives as SPR sensitizers.

“…Ongoing studies clearly indicate that there are too many papers on pesticide detection properties of MPc-based materials. [30][31][32][33][34] For instance, Ribeiro F.W.P. and his co-workers have modified a CoPc-fMWCNT/GCE sensor electrode to sense the formetanate hydrochloride.…”

In this paper, new metallophthalocyanines (MPc) were synthesized by cyclotetramerization of 4-{[4-(2-morpholin-4-ylethoxy)benzyl]oxy}phthalonitrile. To increase potential application of MPcs, redox active Co(II), Mn(III) and Ti(IV)O metal centers were preferred. MPcs were decorated with redox active and electropolymerizable {[4-(2-morpholin-4-ylethoxy)benzyl]oxy} substituents in order to coat the complexes with electropolymerization. Synthesized MPcs were characterized with UV-Vis, IR, 1H-NMR, 13C-NMR and MS (ES+ and MALDI-TOF) spectroscopies and voltammetry and in situ spectroelectrochemistry techniques. Voltammetric and in situ spectroelectrochemical analyses indicated that all complexes gave metal based reduction processes in addition to the Pc based processes. During oxidation reaction, all complexes were coated on the glassy carbon electrode (GCE) surface with oxidative electropolymerization reactions. Redox active and conductive GCE/MPc electrodes were constructed with the electropolymerization of MPcs and these electrodes were tested as active pesticide sensors for eserine, parathion, diazinon and fenitrothion pesticides. CoPc did not interact with any pesticide compound while MnPc and TiOPc selectively sensed diazinon and eserine, respectively.

“…They also exhibit a strong doublet band in the visible region at 633 and 670 nm, referred to as the Q band of CuPc‐SO 3 − , originated due to the π–π* transition of the phthalocyanine ring. The doublet band is due to the contribution of both the aggregated and individual units of CuPc‐SO 3 − [29–34] …”

Enhanced Four‐Electron Selective Oxygen Reduction Reaction at Carbon‐Nanotube‐Supported Sulfonic‐Acid‐Functionalized Copper Phthalocyanine

In the present work, the oxygen reduction reaction (ORR) is explored in an acidic medium with two different catalytic supports (multi‐walled carbon nanotubes (MWCNTs) and nitrogen‐doped multi‐walled carbon nanotubes (NMWCNTs)) and two different catalysts (copper phthalocyanine (CuPc) and sulfonic acid functionalized CuPc (CuPc‐SO3−)). The composite, NMWCNTs‐CuPc‐SO3− exhibits high ORR activity (assessed based on the onset potential (0.57 V vs. reversible hydrogen electrode) and Tafel slope) in comparison to the other composites. Rotating ring disc electrode (RRDE) studies demonstrate a highly selective four‐electron ORR (less than 2.5 % H2O2 formation) at the NMWCNTs‐CuPc‐SO3−. The synergistic effect of the catalyst support (NMWCNTs) and sulfonic acid functionalization of the catalyst (in CuPc‐SO3−) increase the efficiency and selectivity of the ORR at the NMWCNTs‐CuPc‐SO3−. The catalyst activity of NMWCNTs‐CuPc‐SO3− has been compared with many reported materials and found to be better than several catalysts. NMWCNTs‐CuPc‐SO3− shows high tolerance for methanol and very small deviation in the onset potential (10 mV) between the linear sweep voltammetry responses recorded before and after 3000 cyclic voltammetry cycles, demonstrating exceptional durability. The high durability is attributed to the stabilization of CuPc‐SO3− by the additional coordination with nitrogen (Cu‐Nx) present on the surface of NMWCNTs.
