Cross-sensitive chemical sensors based on tetraphenylporphyrin and phthalocyanine

Voltammetric and spectroelectrochemical properties of titanylphthalocyanines bearing catecholato and naphthalenediolato moieties

“…8B inset). These spectroscopic changes support the intra-and intermolecular coordinations of Pd 2+ ion with the S donor atoms of the substituents of 2 [1,2,[8][9][10][11][29][30][31].…”

“…The sulfur groups on the periphery of the metallophthalocyanine complexes are sensitive to soft metal ions, such as Ag + and Pd 2+ [8][9][10][11][33][34][35]. Therefore, we have employed voltammetric and UV-vis spectroscopic titrations to monitor the capability of our MPcs for sensing/ coordinating transition metal ions of different sizes.…”

“…The family of reactive phthalocyanine molecules has been an interesting target for the development of further chemical reactions [1,[3][4][5][6][7][8]. Designed peripheral moieties on the phthalocyanines bearing hetero-atoms (N, O, S) are used to bind an exocyclic metal ion, design desired geometries and confer solubility [1][2][3][8][9][10][11].…”

“…Designed peripheral moieties on the phthalocyanines bearing hetero-atoms (N, O, S) are used to bind an exocyclic metal ion, design desired geometries and confer solubility [1][2][3][8][9][10][11]. The choice of TiOPc complexes is based on the fact that TiPc containing a d 0 metal will also have enhanced triplet yields.…”

Potential Aluminium(III)- and Gallium(III)-selective Optical Sensors Based on Porphyrazines

“…11,12 Solvent polymeric membrane sensors based on porphyrin and phthtalocyanine systems have been investigated for a broad range of mono-and di-valent cations. 13 Porphyrazines substituted in the periphery have myriad potential applications as photosensitizers for photodynamic therapy of cancer, 14 gas and metal ion sensors, 15 molecular conductors 16 and non-linear optical materials. 17 Phthalocyanines, while interacting with a Lewis acid (e.g.…”
