“…If the rare-earth tris(-diketonates) are used as the rare-earth ion source ( Figure 4), their reaction with the metal-free Pc could be conducted in DMSO without any organic base (Scheme 3, conditions 3a). Unsubstituted rare-earth Pcs 1 were prepared under these conditions with high, up to 86%, yields ( 2 ] complexes are the major products in the reaction between dilithium Pc and rareearth diketone in acetone [106][107][108][109]. In addition, these complexes were also obtained in THF [107] or as a minor reaction product in DMSO [104,110].…”

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].

“…[15][16][17][18][19][20][21][22][23][24][25][26][27] Metallophthalocyanines in which the central atom has a valence of three or more are known to possess one or two out of plane axial ligands. [28][29][30][31] We recently reported the synthesis of zirconium and hafnium phthalocyanine complexes with various β-diketones and polyphenols which were made by replacing the two Cl -ions of the dichloro(phthalocyanine) complexes with organic ligands [17,23,24,27] and this was followed by a preliminary electrochemical study on some of these compounds. [32] The present work is a continuation of these studies and involves the electrochemical and spectroelectrochemical characterization of fourteen related Zr IV and Hf IV derivatives whose structures are shown in Chart 1.…”

“…In mono-phthalocyaninate complexes [Ln(Pc)(acac)] and [Ln(Pc)(acac) 2 ] À , one oxidation and two reduction processes are seen; the half-wave potentials of oxidation and of the first reduction are quasi-insensitive to the nature of the Ln ion, while that of the second reduction step increases with increasing charge density on the metal ion. 222 A study of similar complexes with other b-diketonate ancillary ligands confirms, by EPR measurements, the radical nature of the macrocycle and the various redox steps have been characterized by electronic absorption spectroscopy. 223…”
