“…In Pb(Pc) and other common metallophthalocyanines, only four or five bands, characteristic of phthalocyanine ring deformations, are evident between 700 and 360cm Ϫ1 . For Pb(Pc), [1] they lie at 627, 560, 497, and 436 cm Ϫ1 . In the spectrum 6b, we observe 13 bands between 360 and 650 cm Ϫ1 .…”

“…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]isoindolediylidenenitrilo [1]isoindolyl [3]ylidenenitrilo)phthalocyan- ine. [9] For simplification, in reference [7] and subsequent papers, Janczak et al named the bicyclic macrocycle in compound 3 as Pcc, and this name is now an accepted abbreviation of this hexapyrrole ligand.…”

“…In order to have the substitution prefixes as small as possible, we started the numbering of the carbon atoms from a bridgehead carbon. With this numbering scheme, compounds 2 and 3 are named NbCl(1,16-Pcc) and M(1,17-Pcc) (M ϭ Gd, In, Tl), respectively, and 1 is named Bi (1,. There are some advantages in this numbering scheme: a) The indices are independent of the clockwise or anticlockwise sequence and of the bridgehead carbon atom chosen as number one; b) The second index directly indicates the number of benzopyrrole moieties between the two bridgehead carbon atoms, each benzopyrrole moiety being made up of eight carbon atoms.…”

“…Our assignments were made based on literature reports [37,41Ϫ51] and by comparison with those made for Pb(Pc). [1,27] Some very intense and fairly intense bands characteristic of Pb(Pc) are evident in the spectrum of Bi(1,24-Pcc), with only a slight modification. These are for Pb(Pc)/Bi(1,24-Pcc), respectively: bands at 725/720 cm Ϫ1 [out-of-plane CϪH deformations γ(CϪH) [27] ], 772/774 cm Ϫ1 [CϪN stretching vibration in pyrrole skeleton, ν(CϪN)], 950/953 cm Ϫ1 and that at 1003/997 cm Ϫ1 , the band at 1080/1065 cm Ϫ1 and that at 1161/1162 cm Ϫ1 both assigned to CϪN stretching vibration, and the bands at 1282/1299 and 1479/1482 cm Ϫ1 , all in the range of the CϪC stretching vibration frequencies in the isoindole skeleton, ν(CϪC).…”

“…The complete resolution of the molecular structure of a neighbouring yellowϪgreen complex, the bicyclophthalocyaninatochloroniobium(IV), [Nb(C 48 H 24 N 13 )Cl] (2) was reported for the first time by Gingl and Strähle. [5] Janczac and Kubiak obtained other green bicyclophthalocyanine complexes, M III (C 48 H 24 N 13 ) 3, with indium(III), other bicyclic ligands already reported in the literature are named (1, and (1,. The molecular structure of Bi (1, 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.…”

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.

Unlike electronics, which is based on the freedom of the charge of an electron whose memory is volatile, spintronics is based on the freedom of the charge, spin, and orbital of an electron whose memory is non-volatile. Although in most GMR, TMR, and CMR systems, bulk or classical magnets that are composed of transition metals are used, this Focus Review considers the growing use of single-molecule magnets (SMMs) that are composed of multinuclear metal complexes and nanosized magnets, which exhibit slow magnetic-relaxation processes and quantum tunneling. Molecular spintronics, which combines spintronics and molecular electronics, is an emerging field of research. Using molecules is advantageous because their electronic and magnetic properties can be manipulated under specific conditions. Herein, recent developments in [LnPc]-based multiple-decker SMMs on surfaces for molecular spintronic devices are presented. First, we discuss the strategies for preparing single-molecular-memory devices by using SMMs. Next, we focus on the switching of the Kondo signal of [LnPc]-based multiple-decker SMMs that are adsorbed onto surfaces, their characterization by using STM and STS, and the relationship between the molecular structure, the electronic structure, and the Kondo resonance of [TbPc(2)]. Finally, the field-effect-transistor (FET) properties of surface-adsorbed [LnPc(2)] and [Ln(2)Pc(3)] cast films are reported, which is the first step towards controlling SMMs through their spins for applications in single-molecular memory and spintronics devices.
