Asararenes - A family of large aromatic macrocycles [PDF]
, 2013 We announce the establishment of a new family of macrocycles - the asararenes, which are based on para-methylene linked "asarol methyl ether" (1,2,4,5-tetramethoxybenzene) units.

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces
Angewandte Chemie, EarlyView.Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...

Quartz Microbalance Sensor for the Detection of Acrylamide
Sensors, 2004 : Several macrocycles of the Hunter-Vögtle type have been identified as superior host compounds for the detection of small amounts of acrylamide. When coated onto the surface of a quartz microbalance, these compounds serve as highly sensitive and ...

Recent Advances in the Synthesis and Applications of Nitrogen-Containing Macrocyclic Arenes
MoleculesMacrocyclic arenes are rich-electron macrocycles bridged by methylene or methyl groups from aromatic rings substituted by hydroxyl or alkoxy groups. It has attracted great interest in host–guest chemistry and supramolecular self-assembly due to its clear

Crystal structure of the N-benzyloxycarbonyl-Alanyl-Phenylalanyl-methyl ester: the importance of the H-bonding pattern [PDF]
, 2011 Large crystals of the methyl ester of the N-a-benzyloxycarbonyl protected Ala-Phe dipeptide (Z-AF-OMe) were obtained after the very slow evaporation of a solution of the corresponding carboxylic acid (Z-AF-OH) in methanol containing an excess of HCl. The

A membrane permeability database for nonpeptidic macrocycles
Scientific DataThe process of developing new drugs is arduous and costly, particularly for targets classified as “difficult-to-drug.” Macrocycles show a particular ability to modulate difficult-to-drug targets, including protein-protein interactions, while still ...
