Radially Oriented [ n]Cyclo- meta-phenylenes
Castro, Edison,Mirzaei, Saber,Hernández Sánchez, Raúl
, p. 87 - 92 (2021)
Molecular compounds with zigzag carbon nanotube geometries are exceedingly rare. Here we report the synthesis and characterization of carbon-based nanotubes with zigzag geometry, best described as radially oriented [n]cyclo-meta-phenylenes, extending the tubularene family of compounds. By the incorporation of edge-sharing benzene rings into the tubularene's radial π-surface, we have uncovered the first step to give rise to the emergence of radial orbital distribution in zigzag nanorings.
C-pentyltetra(3-pyridyl)cavitand: A versatile building block for the directed assembly of hydrogen-bonded heterodimeric capsules

Hydrogen-bond-directed assembly of heterodimeric cavitand-based capsules is of considerable interest. Herein, we report the synthesis and single-crystal X-ray structure determination of a pyridyl-functionalized cavitand that contains suitable hydrogen-bond acceptor moieties for the construction of asymmetric cavitand-based capsules.

A simple and straightforward regioselective synthesis of distal disubstituted resorcin[4]arenes was developed, avoiding competing substitution patterns at an early stage via regioselective deactivation. Product limiting reaction steps were optimized by st
A reactive and environmentally friendly protocol for expeditious synthesis of various resorcinarenes using zinc hydrogen sulfate

, p. 377 - 381 (2019/04/03)
In this work, for the first time, metal hydrogen phosphates and sulfates have been studied as effective solid acid catalysts for the condensation of resorcinol with aromatic and aliphatic aldehydes to give tetrameric cyclic products, resorcinarenes, which
Calixarene-mediated liquid-membrane transport of choline conjugates
Adhikari, Birendra Babu,Fujii, Ayu,Schramm, Michael P.
supporting information, p. 2972 - 2979 (2014/05/20)
A series of supramolecular calixarenes efficiently transport distinct molecular species through a liquid membrane when attached to a receptor-complementary choline handle. Calix[6]arene hexacarboxylic acid was highly effective at transporting different target molecules against a pH gradient. Both carboxylic-and phosphonic-acid-functionalized calix[4]arenes effect transport without requiring a pH or ion gradient. NMR binding studies, two-phase solvent extraction, and three-phase transport experiments reveal the necessary and subtle parameters to effect the transport of molecules attached to a choline "handle". On the other hand, rescorin[4]arene cavitands, which have similar guest recognition profiles, did not transport guest molecules. These developments reveal new approaches towards attempting synthetic-receptor-mediated selective small-molecule transport in vesicular and cellular systems.
Towards allosteric receptors - Synthesis of Resorcinarene-Functionalized 2,2′-Bipyridines and their metal complexes
Staats, Holger,Eggers, Friederike,Hass, Oliver,Fahrenkrug, Frank,Matthey, Jens,Luening, Ulrich,Luetzen, Arne
scheme or table, p. 4777 - 4792 (2009/12/25)
Based on a first: example of an allosteric hemicarcerand (1) we prepared four new 2,2′bipyridines that carry resorcinarene moieties in a highly convergent manner. Upon coordination to suitable transition metal ions or their complexes these compounds undergo conformational changes in a way that: they switch between "open" and. "closed" forms (2, 3, and 4) or vice versa (5), thus, bringing together or separating the two functional, moieties on the central, bipyridine, Among the transition metal complexes that act: as effectors for the conformational switching, [Re(CO)5Cl] and monomeric copper(I) complexes of sterically hindered 2,9-arylated 1,10-phenanthrolines proved, to be very effective.
