Helical metallohost-guest complexes via site-selective transmetalation of homotrinuclear complexes.
TLDR
The site-specific metal exchange of trinuclear complex [LZn3]2+ described here will be utilized for highly selective ion recognition, site-selective synthesis of (3d)2(4f) trimetallic complexes, and construction of "tunable" metallohelicenes.
Synthesis of figure-of-eight helical bisBODIPY macrocycles and their chiroptical properties.
A macrocyclic bisBODIPY (bis(boron-dipyrromethene)) complex [1B2] with a figure-of-eight helicity was synthesized and successfully resolved. [1B2] was proven to be one of the most efficient
Synthesis, Ion Recognition Ability, and Metal-Assisted Aggregation Behavior of Dinuclear Metallohosts Having a Bis(Saloph) Macrocyclic Ligand.
TLDR
Density functional theory calculations revealed that smaller metal ions do not occupy the center of each macrocycle in the sandwich structures 22M, while larger Cs(+) simultaneously interacts with all the 12 oxygen donor atoms, which explains the preference for 2·Na over 22Na.
A facile and high-yield formation of dipyrrin-boronic acid dyads and triads: a light-harvesting system in the visible region based on the efficient energy transfer.
TLDR
Interestingly, the fluorescence quenching process in the excited state of the triad 3·5 took place following the energy transfer event, indicating appropriate positioning of the energy donor and acceptor is necessary to construct a highly efficient FRET system.
Modulation of multimetal complexation behavior of tetraoxime ligand by covalent transformation of olefinic functionalities.
TLDR
The chemical transformation of the olefinic moiety significantly affects the multimetal complexation behavior of the tetraoxime ligands and significantly deforms the structure in such a way that one of the salicylaldoxime moieties does not participate in the coordination.
Multiple folding structures mediated by metal coordination of acyclic multidentate ligand.
Four kinds of folded structures are formed upon the metal complexation of a bis(N(2)O(2)) ligand in which two oxime-type N(2)O(2) chelate ligands are connected by a flexible diethyleneoxy linker. The
Novel thiosalamo ligand as a remarkably stable N2S2 salen-type chelate and synthesis of a nickel(II) complex.
Novel N2S2 tetradentate chelate ligand H2tsalamo, which contains both thiol groups and C=N moieties, was synthesized as a remarkably stable compound. Complexation between H2tsalamo and nickel(II)
Activation of invariant natural killer T cells stimulated with microbial α-mannosyl glycolipids
TLDR
These results suggest that these microbial α-mannosyl glycolipids are capable of being recognized by both the invariant TCR and PRRs and inducing immune responses.
