Artificial light-harvesting antennae of coordination-organized macrocyclic porphyrin pentamer and hexamer are visualized by high resolution scanning tunneling microscopy (HRSTM) on a gold surface.

The fully functionalized macrocyclic core of the marine natural product iriomoteolide-1a has been successfully constructed in a convergent and enantioselective manner.

a pvc membrane fe(iii) ion selective electrode has been constructed using a new macrocyclic asmembrane carrier.the electrode exhibits a good potentiometric response for fe(iii) over a wideconcentration range 1.0×10-4 to 1.0×10-1m with a slope 19.4±0.5 mv/decade a and a working phrange of 6.5-9.0. it has a fast response time ≤30s.the best performance was observed with themembrance having the 30....

Steroid-based receptors with enclosed binding sites, formed from quaternary ammonium and macrocyclic bis-urea units, can substantially override the Hofmeister series in anion phase transfer experiments.

The macrocyclic host cucurbit[7]uril exhibits highly specific inhibitory effects on the activity of proteases, which can be analyzed by a host-substrate complexation model.

Correction for 'Triamide macrocyclic chloride receptors via a one-pot tandem reduction-condensation-cyclization reaction' by Harekrushna Behera, et al., Org. Biomol. Chem., 2017, DOI: .

in this research work, we report the synthesis of macrocyclic diamides from the reaction of diesters and aliphatic diamines in the presence of caesium carbonate. it has been demonstrated that among the carbonate of alkali metals (li2co3, na2co3, k2co3 and cs2co3), cs2co3 appear to be the best catalyst for macrocyclization. diesters with different substitution patterns on the aromatic ring react...

Macrocyclic planar tris-dipyrrin BF(2) complexes exhibit strong alkali-metal recognition and pseudorotaxane formation ability with a secondary ammonium salt through BF(2)-cation interactions.

CpCo(CO)2-mediated cyclotrimerisation of bis-alkynes and cyanamides provides multisubstituted 2-aminopyridines, including macrocyclic products, such as 22 (50% yield).

A 22-membered macrocyclic discodermolide/dictyostatin hybrid has been designed and synthesised; biological evaluation against a range of human cancer cell lines revealed significant levels of growth inhibition.
