Diphthalocyaninatolanthanum as a New Phthalocyaninato‐Dianion Donor for the Synthesis of Heteroleptic Triple‐Decker Rare Earth Element Crown‐Phthalocyaninato Complexes

Abstract

(Pc). In contrast to the highly hygroscopic Li 2 (Pc), La(Pc) 2 is quite air-stable and its use allowed a significant

Synthesis and Study of Physicochemical Properties of New Substituted Tetrathieno[2,3-b]porphyrazines

“…The triple-decker complex 6 exhibits Q-band splitting and a hypsochromic shift of the main absorption maximum as compared to those of monoporphyrazines. Similar features have been previously reported for triple-decker phthalocyanine complexes [16,17] and are due to the interaction of the inner and external deck. [13] The spectra of porphyrazines 2-5 in a non-coordinating solvent (C 6 H 6 ) exhibit aggregation behaviour that is (Table 1).…”

Synthesis, crystal structure and self-assembly property of a mixed (phthalocyaninato) (porphyrinato) europium triple-decker complex

“…To solve this problem, obtaining the single crystal molecular structure seems to play important role. However, the single crystals of these mixed phthalocyaninato and porphyrinato triple-decker rare earth complexes remain rare [8][9][10]. Particularly, to the best of our knowledge, the mixed ring triple-deckers containing one porphyrin ligand are only limited to {(Pc)Eu(Pc)Eu[T(4-OCH 3 )PP)]} [11] and {PcCe[T(4-OCH 3 )PP)]CePc} [12].…”

Reactivity of Rare Earth Metal Porphyrins/Phthalocyanines in Acid Media

“…There are structural data on In 2 (Pc) 3 , [75] Lu complex with tetra-15-crown-5-phthalocyanine [18] and few heteroleptic porphyrin/ phthalocyanine complexes. [76] The first structure reported for a heteroleptic triple-decker crown-phthalocyaninato complex was represented in the work [77] on an example of a complex (Pc)Sm[(15C5) 4 Pc]Sm(Pc). The central ligand in Lu complex is turned to 43.7 0 about external ligands.…”

“…Average distances between Lu atoms and coordinating N atoms of external ligands are equal 2.305 Å. Analogous distances to the central ligand N atoms are much larger (2.560 Å). According to the X-ray data, [77] (Pc)Sm[(15C5) 4 Pc]Sm(Pc) has a symmetrical structure with two Sm atoms located at a nonbonding Sm-Sm distance of 3.5111(4) Å. The distances between the samarium and nitrogen atoms are determined as 2.613(3) and 2.599(3) Å for the central bridging crown-substituted macrocycle and as 2.372(3), 2.385(3), 2.397(3) and 2.395(3) Å for the outer Pc ligands.…”
