Shape-Persistent [4+4] Imine Cages with a Truncated Tetrahedral Geometry
Lauer, Jochen C.,Zhang, Wen-Shan,Rominger, Frank,Schr?der, Rasmus R.,Mastalerz, Michael
, p. 1816 - 1820 (2018)
The synthesis of shape-persistent organic cage compounds is often based on the usage of multiple dynamic covalent bond formation (such as imines) of readily available precursors. By careful choice of the precursors geometry, the geometry and size of the resulting cage can be accurately designed and indeed a number of different geometries and sizes have been realized to date. Despite of this fact, little is known about the precursors conformational rigidity and steric preorganization of reacting functional groups on the outcome of the reaction. Herein, the influence of conformational rigidity in the precursors on the formation of a [4+4] imine cage with truncated tetrahedral geometry is discussed.
A new tripodal receptor for molecular recognition of monosaccharides. A paradigm for assessing glycoside binding affinities and selectivities by 1H NMR spectroscopy

A new tripodal receptor for the recognition of monosaccharides is described. The prototypical host 1 features a 1,3,5-substituted 2,4,6-triethylbenzene scaffold bearing three convergent H-bonding units. The binding ability of the t-octyl derivative 1a tow
Hydrogen and halogen bonding in the crystal structure of a 1,3,5-substituted 2,4,6-triethylbenzene consisting of three phenanthroline units
Mazik, Monika,Hartmann, Andre,Jones, Peter G.
, p. 458 - 463 (2010)
1,3,5-Tris-[N-(l,10-phenanthrolin-2-yl-carbonyl)aminomethyl]-2,4, 6-triethylbenzene (1) was synthesized, and its crystal structure was examined. X-ray structural analysis revealed the presence of hydrogen-bonded water molecules as well as hydrogen- and halogen-bonded chloroform, molecules in the crystal structure of 1. The 1-H2O-CHCl3 associate is stabilized, by N-H...O, O-H...N, O-H...O, C-H...O, and C-H...Cl hydrogen bonds as well as C-Cl...O, C-Cl...π, and C-Cl...Cl interactions. Particularly short C-H...O hydrogen bonds with H...-O and C...O distances of 1.89 and 2.94 , respectively, are observed in the crystal structure. The H...O distance is approximately 30% shorter than the sum of the van der Waals radii of involved atoms.

Capitan-Vallvey, Luis Fermin,Arroyo-Guerrero, Eduardo,Fernandez-Ramos, Maria Dolores,Santoyo-Gonzalez
, p. 4459 - 4466 (2005)
A new optical absorption-based disposable sensor for nitrate is described. The nitrate-sensitive element is a bicyclic cyclophane receptor next to a suitable pH-sensitive lipophilic dye immobilized in a plasticized polymeric membrane. The rigid amide-base
A synthetic receptor selective for citrate
Metzger,Lynch,Anslyn
, p. 862 - 865 (1997)
Applied molecular recognition strong and selective binding of citrate in highly competitive media such as water and orange juice is reported. Five steps are enough to synthesize receptor 1 that is complementary in charge and shape to citrate. Electrostati
Compounds Combining a Macrocyclic Building Block and Flexible Side-Arms as Carbohydrate Receptors: Syntheses and Structure-Binding Activity Relationship Studies
Amrhein, Felix,Mazik, Monika
, p. 6282 - 6303 (2021/09/18)
A series of new representatives of compounds combining a macrocyclic building block and flexible side-arms were prepared and their ability to act as carbohydrate receptors evaluated. The target compounds were obtained by multi-step syntheses, which included the preparation of numerous precursors as well as the isolation of a large number of by-products. The structure-binding activity relationship studies comprise, in particular, the variation of the side-arms in order to demonstrate the importance of the presence of a hydrogen bond donor in these units for the effective complexation of carbohydrates. Based on the findings of our previous studies, the variation of the bridge units is limited to benzene- and pyrrole-based moieties, whereby the use of the last-mentioned bridge type was expected to produce more effective systems. This assumption was confirmed by 1H NMR titrations and isothermal titration calorimetry.
