“…27,505,506 In addition, it has been theoretically predicted that SubPcs could be effective for the detection of I − , Br − , and BF 4 − ions. 507 SubPcs have also been successfully employed for the analysis of red wines, 25 the determination of catechin in tea extracts, 140 the assay of acetylsalicylic acid in the drug Cardiomagnyl, 508 and for the sensing of pesticides. 509 Interestingly, the Park's group recently reported a new strategy for the selective detection of sulfide anion, which is based on anion–π non-covalent interactions between the sulfide and the π-cloud of fluorinated SubPcs.…”

“…The development of high-performance organic materials with extensive applications has become an important field of research. [1] Recently, the interest on subphthalocyanine (SubPc) and their derivatives has been enlarged because of their multiple technological applications which include organic optoelectronics [2,3,4] . As a typical phthalocyanine compound, the SubPc consists of three isoindole units and has a delocalized 14 π-electrons conjugation system, processing a conical bowlshaped structure with non-central symmetry [5] .…”

Two novel substituted subphthalocyanines have been prepared introducing m‐hydroxybenzoic acid and m‐hydroxyphenylacetic acid into the axial position of bromo‐subphthalocyanine. The compounds have been characterized by Fourier transform infrared (FT‐IR), Nuclear Magnetic Resonance (NMR) and single‐crystal X‐rays diffraction (XRD) methods. Their photophysical properties show that the axial substitution results into a relatively higher fluorescence quantum efficiency (ΦF=5.74 for m‐hydroxybenzoic acid and 9.09 % for m‐hydroxyphenylacetic acid) in comparison with that of the prototype compound, despite the almost negligible influence on the maximum absorption or the emission position. Moreover, the electrochemical behaviors show that the axial‐substituted subphthalocyanines also exhibit enhanced specific capacitances of 395 F/g (m‐hydroxybenzoic acid) and 362 F/g (m‐hydroxyphenylacetic acid) compared with 342 F/g (the prototype) to the largest capacitance at the scan rate of 5 mV/s, and the significantly larger capacitance retentions of 83.6 % and 82.1 % versus 37.3 % upon density up to 3 A/g. These results show the potential of these axial‐substituted subphthalocyanines in the use as organic photovoltaics and supercapacitors.

“…SubPcs were widely investigated as prospective materials in different application fields, among them organic light-emitting diodes [28], organic photovoltaic [29][30][31][32] and non-linear optics [33]. Subphthalocyanines have attracted much attention in the field of sensors due to their optic properties, related with an intense Q absorption band.…”

“…Colorimetric and fluorometric cyanide sensors based on subphthalocyanines with electron-withdrawing substituents (nitro-and fluorinegroups) were successfully prepared [34]. An ion selective electrode for the salicylate ion, based on phenoxy-substituted subphthalocyanines has recently been described [33].…”

The electron mediator properties of three subphthalocyanines (SubPcs) [hexa-chloro boron subphthalocyanine (ClSubPc), tri-tert-butyl boron subphthalocyanine (t-BuSubPc) and hexa-phenoxy boron subphthalocyanine (PhOSubPc)] in Tyrosinase and Laccase biosensors (deposited on ITO glass) for the detection of catechol and hydroquinone were evidenced. A particularly remarkable performance was observed in the PhOSubPc-Tyr sensor, which takes account of the p-p interactions between subphthalocyanine rings and the active sites of the enzymes. Mediated electron transfer between redox enzymes and the ITO electrode improved the limits of detection by one order of magnitude, reaching 10 À7 molÁL À1 values. Studies at increasing scan rates confirmed the improvement of the charge transfer rates caused by the presence of the SubPcs. A bioelectronic tongue formed by an array of the SubPc based biosensors has been able to discriminate red wines according to their Total Polyphenol Index.
