A sandwich clamshell-type phthalocyaninato quadruple-decker binuclear lutetium(III) complex: Synthesis and spectral properties

Rare-earth based tetrapyrrolic sandwiches: chemistry, materials and applications

“…104 To form well-defined dimeric bisphthalocyaninates the starting clamshell ligand can be treated with lanthanide monophthalocyaninates. 105,106 With a diterbium complex (tBu 4 Pc)Tb[c-Pc 2 ]Tb(tBu 4 Pc) as the example ferromagnetic intermetallic interactions were observed leading to elongation of magnetic relaxation times in comparison with the monomeric terbium complex Tb(tBu 4 Pc) 2 (cf. Section 3.3.1).…”

Lanthanide–tetrapyrrole complexes: synthesis, redox chemistry, photophysical properties, and photonic applications

“…29, top). 25 In 2020, Martynov et al reported potassium-induced dimerization of heteroleptic triple-decker crown-phthalocyaninates [(15C5) 4 Pc]Ln(Pc)Ln(Pc) (Ln = Y, Tb; Fig. 29, middle).…”

“…The 1 : 1 and 1 : 2 (Ln : L) geometries are the commonest, followed by triple deckers ideally suited for the study of magnetic interactions since the Ln-Ln distance is rather short (B0.35 nm); although less observed, the 2 : 2 stoichiometry also yields interesting f-f assemblies. [22][23][24] More elaborate structures such as quadruple-decker 2 : 4 complexes 25 in which two double-decker units are linked by a diethoxybenzyl unit 26 have also been explored, as well as 4 : 5 bimetallic 4d-4f quintuple deckers. 27 Although lanthanide tetrapyrrole complexes are regularly mentioned in review articles dealing with one or another aspect of 4f-element coordination chemistry, 28 supramolecular chemistry, 29,30 photo-and spectro-chemistry, [31][32][33][34] liquid crystals, 35 analytical 10,36 or bio-applications, 4,37 non-linear optical properties, 38 and magnetism, 39 the field itself has seen a few comprehensive reviews during the past 20 years, since the publication of the Porphyrin Handbook.…”

Two‐Dimensional Metallophthalocyanine Nanomaterials for Electrocatalytic Energy Conversion

“…[35,36] While metal ions with much higher coordination numbers (i.e., rare earth metals) have larger ionic radii and may form sandwich-like metal complexes (symmetry/asymmetry). [37,38] Due to π-π interactions, MPcs are capable to show low-dimensional inferior conductivity along the column direction after crystallization. [39] With the charge increase of the central ions, more electric field strength and higher ion potential are obtained.…”
