“…As a result, electronic coupling between the rare-earth centers in these multiple-decker compounds decreases with an increase in the number of Pc ligands and their magnetic properties start to resemble classic rare-earth double-decker systems. These multipledecker systems, with rare-earth ion size-dependent intramolecular electronic coupling between macrocycles, as well as metal-metal interactions (in the case of multinuclear rare-earth compounds), open potential applications for such compounds in electrochromic modules [30,43,44], gas sensors [30,[44][45][46][47][48][49][50], metal ion sensors [51], and bio-sensors [51][52][53][54], as well as active components of molecular magnets [33,[55][56][57][58][59][60], materials for multi-bit information storage [61][62][63][64], molecular electronics [33,[65][66][67], and non-linear optics [30,[68][69][70].…”

New developments as well as a historic overview on synthetic strategies for preparation of the rare-earth complexes with porphyrins, phthalocyanines, naphthalocyanines, tetraazaporphyrins, and related systems are discussed in detail with emphasis on selective synthetic pathways for preparation of single-, double, and triple-decker architectures. 6 IntroductionAfter their discovery almost 100 years ago, phthalocyanines (Pcs) were predominantly investigated because of their industrial applications as dyes, pigments, and catalysts [1][2][3].Similarly, historically, porphyrins (Pors) were intensively studied because of their importance in mimicking biologically relevant atom-and electron-transfer processes as well as light-harvesting mechanisms associated with living cells [4][5][6]. In addition, porphyrins, phthalocyanines, and their analogues were found to be useful in applications such as redox-driven fluorescence markers and biomarkers, light-harvesting antennas for organic photovoltaics and dye sensitized solar cells, charge carriers for copiers and printers, materials for molecular electronics, as well as redoxactive components in environmental, biological, and industrial sensors as well as active components in photodynamic therapy (PDT) and boron neutron therapy (BNT) of cancer [7][8][9][10][11][12][13][14][15][16][17][18][19].In their initial attempts, researchers focused on rich coordination, redox, and magnetic properties of the metal-free, main-group, and especially transition-metal porphyrinoids. It was soon realized, however, that the rare-earth ions can form unusual systems when coupled with the phthalocyanine ligand.The first rare-earth Pcs were reported by Russian scientists Kirin and Moskalev in 1965 [20]. Kirin and Moskalev also pointed out that because of the large ionic radii and high coordination numbers of the rare-earth ions, the formation of the double-decker rare-earth phthalocyanine compounds could be achieved under specific reaction conditions [20,21]. During the next 50 years, it was confirmed that rare-earth ions are capable of the formation of phthalocyanine single-, double, and triple-decker complexes and their analogues [22][23][24][25][26][27][28][29][30][31][32][33]. One of the interesting recent discoveries was the preparation and characterization of heteronuclear (rareearth / cadmium) multiple-decker complexes, which contain up to six Pc ligands [34][35][36][37][38][39][40][41][42].

“…The detection limit of NADH and vitamin C was found to 0.05 and 0.03 mM, respectively. This value for NADH is one order of magnitude smaller than one previously obtained with a spun film of dysprosium(III) derivative [21]. Vitamin C in the range 0.4 -6.0 mM was recently detected using a probe of graphene nano-sheets immobilized on pyrolysed photoresist film.…”

“…The theme of this investigation stems from our recent work on exploitation of the electrochromic behaviour of bis[octakis(hexylthio)phthalocyaninato] dysprosium(III) spun films on indium tin oxide-coated glass substrates for ex situ detection of NADH having concentrations from 10 24 M to 5 Â 10 23 M in phosphate buffer aqueous solutions [21]. In situ kinetic measurements have now provided us an additional insight into the mechanism of biorecognition of NADH and vitamin C by R 16 Pc 2 Lu films peculiar to a redox state.…”

Spin-coated films, approximately 100 nm thick, of a newly synthesized bis[octakis(octyl)phthalocyaninato] lutetium(III) complex on ultrasonically cleaned glass substrates exhibit pronounced chemichromic behaviour with potential application in healthcare. In situ kinetic optical absorption spectroscopic measurements show that the phthalocyanine Q-band is red shifted by 60 nm upon oxidation arising from exposure to bromine vapour. Recovery to the original state is achieved by the treatment of the oxidized films with nicotinamide adenine dinucleotide and L-ascorbic acid (vitamin C) in an aqueous solution containing 1.5 M lithium perchlorate. The neutralization process is found to be governed by first-order kinetics. The linear increase of the reduction rate with increasing concentration of cofactors provides a basis for calibration of analyte concentrations ranging from 3.5 mM down to 0.03 mM.

“…Macroheterocyclic tetraazoporphyrin ring complexes known as phthalocyanines (Pcs) have attracted interest over the years in both research and industrial applications due to their flexible structural architecture that allows easy tuning of optoelectronic, electrochemical, photophysicochemical and optical properties. Lanthanide bis(phthalocyanines) (LnPc 2 ) have been employed in a number applications including electrochromic displays, [1,2] electrical conductivity, [3][4][5] electrochromism, [5][6][7][8][9] gas and electrochemical sensing [10][11][12][13][14][15] and optical limiting. [16][17][18][19][20][21][22][23][24][25][26] Other appealing properties stemming from the LnPc 2 complexes include tunable spectroscopic, electronic and redox characteristics, [27,28] allowing their applications as ambipolar organic field-effect transistors, [29] single molecule magnets, [30,31] supramolecular spin valves [32] and self-assembled nanostructures.…”

In this manuscript, novel green and blue sandwich-type rareearth phthalocyanines (LnPc 2 ) are presented. This parent green LnPc 2 complex is named bis-{2(3),9(10),16(17),23(24)-tetra(4tert-buylphenoxy) phthalocyaninato} neodymium (III) (2) and modified into blue LnPc 2 complexes (3), (4) and (5) based on hexadecyltrimethylammonium ion, mononeodymium(III) diacetate and monodysprosium(III) diacetate as counter ions, respectively. These stable blue lanthanide Pc salts are highly soluble in many organic and inorganic solvents. All complexes 2, 3, 4 and 5 were studied for optical limiting for the first time using Z-scan at nanosecond regime in the visible absorption spectral wavelength (532 nm). Our studies reveal the advantage of exciton coupling in blue sandwich-type rare-earth phthalocyanines over the p-radicals (characterized by blue valence at 485 nm) in the green counterpart which are in resonance with the 532 nm wavelength for optical limiting application. Large singlet ground state to excited state absorption cross section ratios were found, particularly for complex 5 in comparison to that of complex 2.[a] Dr.
