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

“…First examples of such complexes were prepared by Wang et al from (Pc)M(acac), M = Dy and Y and H 2 (SB). 174 Depending on the base used for deprotonation of H 2 (SB) complexes of different nuclearities were obtained. Performing this reaction with Ca(OH) 2 afforded a quadruple-decker complex where the [Ca(MeOH) 2 ] 2+ group bridged two (Pc)M(SB) À units (Scheme 33a), while dinuclear double-deckers (Pc)M[(SB)K(MeOH)] was isolated in the presence of KOH (Scheme 33b).…”

“…Gao et al used dysprosium(III) or erbium(III) monophthalocyaninates generated in situ as templates for condensation of 2,6-diformyl-4-methylphenol and 1,3-diaminopropane to form Scheme 33 Synthesis of mixed-ligand complexes based on half-sandwich phthalocyaninates and Schiff base H 2 (SB) with X-ray structures of the corresponding complexes -from the left to the right: (Pc) 2 Dy 2 (SB) 2 Ca(MeOH) 2 (CCDC FEVDOB), 174 (Pc)Dy(SB)K(MeOH) (CCDC FEVDUH), 174 (Pc)Tb(SB)Zn(Py) 2 NO 3 (CCDC YIMMUE) 175 and (Pc) 2 Dy 2 (CB)(H 2 O) (CCDC XILTOD). 176 This journal is © The Royal Society of Chemistry 2022 unusual trinuclear triple-decker sandwiches with a macrocyclic Schiff ligand and bridging acetate and methoxide counterions M 3 (Pc) 2 (mS)(OAc)(OMe) 2 (Scheme 34b).…”

Synthesis and Characterization of Rare Earth Corrole–Phthalocyanine Heteroleptic Triple-Decker Complexes

“…The design and synthesis of rare earth sandwich complexes with porphyrin and/or phthalocyanine macrocycles has led to various applications of these compounds over the last two decades in the areas of sensors, organic thin-film transistors, − molecular magnets, − nonlinear optical materials, − and nanomaterials. − The ongoing efforts in synthesis and characterization of new triple-decker tetrapyrroles can be attributed in large part to their remarkable optical, electrical, and electrochemical properties that stem from their intriguing inter-ring π–π interactions and f–f interactions of the metal ions. − Previously synthesized triple-decker sandwich complexes with porphyrin and/or phthalocyanine macrocycles not only display a large number of redox states but also exhibit reversible electrochemistry and relatively low oxidation potentials. − For this reason, they have proven to be excellent candidates for multibit molecular information storage devices. − …”
