One‐Pot Formation of Large Macrocycles with Modifiable Peripheries and Internal Cavities

Angewandte Chemie International Edition, 2009
AbstractThe shape of things to come: Aromatic oligohydrazide macrocycles with planar backbones enforced by three‐center hydrogen bonds are formed in high yield from monomeric diacid chlorides and dihydrazides. Macrocycles consisting of six meta‐linked pyridine and benzene residues have an internal cavity of about 10 Å diameter, while those with ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

A Linear Chain of Water Molecules Accommodated in a Macrocyclic Nanotube Channel

, 2016
A macrocyclic tetramer of 2-phenyl-1,3,4-oxadiazole was synthesized, and its self-assembly was investigated. The macrocycle was stacked to form a one-dimensional (1D) columnar structure containing water molecules.

Macrocyclic Chiral Receptors toward Enantioselective Recognition of Naproxen

, 2016
A macrocyclic receptor based on a bischromenylurea and an α,α‘-(o,o‘-dialkyl)diphenyl-p-xylylenediamine spacer provides a C2 chiral cavity to associate carboxylates by H-bonds.

Inherently Chiral Macrocyclic Oligothiophenes: Easily Accessible Electrosensitive Cavities with Outstanding Enantioselection Performances [PDF]

Chemistry – A European Journal, 2014
AbstractLinear conjugated oligothiophenes of variable length and different substitution pattern are ubiquitous in technologically advanced optoelectronic devices, though limitations in application derive from insolubility, scarce processability and chain‐end effects. This study describes an easy access to chiral cyclic oligothiophenes constituted by 12
