“…The substitutive nomenclature of IUPAC is not easy to use. For example, compound 3 in which the trivalent metal is substituted by three hydrogen atoms, is named 29H,31H,35H-19,5-(nitrilo [1,3] Gd, In, Tl); reported in the literature. Our numbering scheme is used for all structures rather than that adopted for substituted phthalocyanine macrocycles 4 ine.…”

“…We recently reported the synthesis and characterisation of a new phase of the triple-decker compound, Bi 2 (Pc) 3 . [1] During the preparation of Bi 2 (Pc) 3 , if reaction mixture was heated to approximately 240 °C and allowed to cool to room temperature, we obtained many bright, orangeϪred crystals. This compound, 1, was characterised by X-ray diffraction as a complex containing six units of phthalonitrile organised in three cycles per bismuth atom.…”

A new orange bicyclophthalocyanine complex of bismuth(III), [Bi(C48H24N13)], has been synthesised by means of the template reaction of bismuth(III) acetate with phthalodinitrile. The ligand consists of the phthalocyanine skeleton, which is bridged by two additional isoindole units. The conjugation of the phthalocyanine ring is interrupted by the two bridgehead sp3‐hybridised carbon atoms. The main difference between this new bicyclophthalocyanine and those previously reported in the literature lies in the position of the bridgehead carbon atoms. In order to differentiate between these bicyclophthalocyaninato complexes, we propose a nomenclature: [Bi(C48H24N13)] is named Bi(1,24‐Pcc), and the other bicyclic ligands already reported in the literature are named (1,16‐Pcc) and (1,17‐Pcc). The molecular structure of Bi(1,24‐Pcc) shows the coordination polyhedron around the bismuth atom, made up of the six isoindole nitrogen atoms of the macrocycle, as a strongly distorted trigonal prism. The two Bi−Niso bonds of the bridge and two of the four Bi−Niso bonds of the (Pc) ring have bond lengths between 2.40 and 2.47 Å. One of the remaining bonds is longer (2.55 Å), and the sixth has a very short length of 2.20 Å. This new complex was fully characterised by UV/Vis and IR spectroscopy, also reported here.

“…Unfortunately, due to a limited amount of synthesized samples, XRD data of Y 2 Pc 3 molecules neither of a single crystal nor a thin film was obtained. However, the XRD data, such as for Bi 2 Pc 3 formed by a sublimed-crystallization, Cd 2 (OAc) 3 (Oac = 1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine) formed by a recrystallization from a solvant, and Tb 2 (obPc) 3 (obPc = dianion of 2,3,9,10,16,17,23, 24-octabutoxyphthalocyanine) in the shape of a single-crystal, were reported, in which we can see a common Pc stacking configuration. For the Bi 2 Pc 3 case, the middle Pc ligand is rotated 38.3° with respect to the top and bottom Pcs.…”

Scanning Tunneling Microscopy Investigation of Tris(phthalocyaninato)yttrium Triple-Decker Molecules Deposited on Au(111)

We studied triple-decker tris(phthalocyaninato)yttrium (Y 2 Pc 3 ) molecules deposited on a Au(111) surface with a low-temperature scanning tunneling microscope (STM). It is shown that the triple-decker molecule can be successfully transferred to the Au(111) surface by a sublimation method in the ultrahigh vacuum condition. A monolayer film of Y 2 Pc 3 is observed with a height of ∼0.55 nm from the bare Au(111) surface. The molecules are adsorbed with a flat-lying configuration and a pseudosquare lattice is formed. Inside each molecule, eight bright protrusions were observed in the occupied-state images, which correspond to the high density-of-state (DOS) area on both sides of four phenyl rings in the top phthalocyanine (Pc). Scanning tunneling spectroscopy (STS) data show distinct features both in occupied and in unoccupied states. The variation of STS spectra when the tip moved from the ligand position to the center of the molecule was small, showing a limited contribution from the center metal.

“…As we discussed above, this suggests that the lower Pc ligand, which attaches to the substrate, has the same bonding configuration as that of the H 2 Pc molecule. To consider the rotations of the middle and top Pc ligand, we examined reported XRD measurements for triple decker molecules, such as Bi 2 Pc 3 ,95 Cd 2 (OAc) 3 (Oac = 1,4,8,11,15,18,22,25‐octakis(hexyl)phthalocyanine),96 and Tb 2 (obPc) 3 (obPc = dianion of 2,3,9,10,16,17,23,24‐octabutoxyphthalocyanine) 55. A common Pc stacking configuration is observed for the triple‐decker Pc molecules.…”

Ever since the first example of a double-decker complex (SnPc2) was discovered in 1936, MPc2 complexes with π systems and chemical and physical stabilities have been used as components in molecular electronic devices. More recently, in 2003, TbPc2 complexes were shown to be single-molecule magnets (SMMs), and researchers have utilized their quantum tunneling of the magnetization (QTM) and magnetic relaxation behavior in spintronic devices. Herein, recent developments in Ln(III)-Pc-based multiple-decker SMMs on surfaces for molecular spintronic devices are presented. In this account, we discuss how dinuclear Tb(III)-Pc multiple-decker complexes can be used to elucidate the relationship between magnetic dipole interactions and SMM properties, because these complexes contain two TbPc2 units in one molecule and their intramolecular Tb(III)-Tb(III) distances can be controlled by changing the number of stacks. Next, we focus on the switching of the Kondo signal of Tb(III)-Pc-based multiple-decker SMMs that are adsorbed onto surfaces, their characterization using STM and STS, and the relationship between the molecular structure, the electronic structure, and the Kondo resonance of Tb(III)-Pc multiple-decker complexes.
