Dimeric BHT-alkoxy magnesium complexes are able to catalyze ROP of lactones and lactides by the binuclear mechanism.
Heterogenized metalloporphyrin catalysts for oxidation reactions are extensively explored to improve chemical production. In this work, manganese meso-tetraarylporphyrins were immobilized on hydrated mesoporous titanium dioxide (SBET = 705 m2 g−1) through carboxylate or phosphonate anchoring groups separated from the macrocycle by 2-arylimidazole linker fused across one of pyrrolic rings macrocycle. The element composition two hybrid materials thus obtained investigated and integrity...
In this work, a previously undescribed phenomenon of orientation-induced redox isomerism in Langmuir monolayer is revealed the case cerium bis-[tetra-(15-crown-5)-phthalocyaninate]-(Ce[(15C5)4Pc]2). It was established that intramolecular electron transfer (IET) from electronic system phthalocyanine to 4f-orbital atom occurs upon spreading (Ce[(15C5)4Pc]2) chloroform solution onto air–water interface (3D → 2D IET). This process related transformation Ce4+ cation Ce3+ monolayer. also found...

The unique properties of porous metal-organic frameworks are responsible for the increasing research interest in design and synthesis this type materials. A general strategy towards targeted possessing desired is a choice optimal linkers, which usually represented by polytopic organic ligands. Porphyrins promising building blocks such due to their tunable physicochemical wide possibilities macrocycle modification. achievements last decade development synthetic approaches porphyrin...
LnCl3(THF)3 (Ln = Y, La ÷ Nd, Sm Lu) readily react with the tridentate 1,3,5-trimethyl-1,3,5-triazacyclohexane (Me3tach) ligand to form mono- or binuclear lanthanide trichloride complexes, depending on stoichiometry of reaction and ionic radius metal: mononuclear pseudosandwich [LnCl3(Me3tach)2], Ho) complexes [Ln2Cl6(Me3tach)3], [LnCl3(Me3tach)(THF)]2 Sm, Tb).

Application of a general and convenient approach to the synthesis heteronuclear crown-substituted triple-decker phthalocyaninates afforded two series complexes containing one dia- paramagnetic Ln(III) ion (for Y almost whole lanthanide family), [(15C5)4Pc]M*[(15C5)4Pc]M(Pc) (or [M*,M] for brevity sake), where (15C5) is 15-crown-5; (Pc(2-)) phthalocyaninato dianion; M ≠ M* = Y, Nd, Eu, Tb, Dy, Ho, Er, Tm, Yb. This consists using LaPc2 as an efficient Pc(2-) source. The solid-state structures...
It was established that isopropyl salicylate can be used similarly to 1,3-diketones as a key component for new efficient extraction system selective separation of alkali metal cations. According DFT modeling complexes and 1,3-diketone with cations (Li+, Na+, K+), six-membered metallacycles are formed whose stability decreases along the series Li > Na K, which results in observed enhanced affinity lithium. The ability is manifested presence trioctylphosphine oxide (TOPO). newly obtained well...
Detection of nitroaromatic compounds (NAC) is an important task since these substances are hazardous to both the biosphere and society. Fluorescent sensors developed for NAC detection usually demonstrate a ‘turn-off’ response analyte, while ‘turn-on’ rarely reported. Here, we present showcase report on new pyrene-imidazoporphyrin dyads that unusual analytic with clear behavior followed by unexpected appearance band, which can be ascribed exciplex emission. The porphyrin backbone dyad also...
