Noncovalent keystone interactions controlling biomembrane structure.
There is a biomedical need to develop molecular recognition systems that selectively target the interfaces of protein and lipid aggregates in biomembranes. This is an extremely challenging problem in supramolecular chemistry because the biological membrane is a complex dynamic assembly of multifarious molecular components with local inhomogeneity. Two simplifying concepts are presented as a fra...
متن کاملTriptycene Structure-Directing Agents in Aluminophosphate Synthesis
The synthesis of aluminophosphates is investigated using a number of triptycene-based organic structure-directing agents (OSDA). These OSDAs are designed to synthesize extra-large pore and/or large cavity-containing molecular sieves. Starting from the hydrophobic triptycene molecule, OSDAs are prepared by introducing three amine-based centers that can be charged either by protonation in the aci...
متن کاملMolecular Structure & Bonding
The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. In order to represent such configurations on a two-dimensional surface (paper, blackboard or screen), we oft...
متن کاملStructure and Bonding
A molecule is formed by the combination of atoms and in the process they attain the electronic configuration of an inert gas. A chemical bond is formed as a result of attraction between the combining atoms. To explain the formation of bonds in diatomic molecules, such as H2, O2, N2, Cl2 etc., it was first suggested by G.N. Lewis that atoms of such molecules attain an inert gas electronic config...
متن کاملBonding in the BaPdSn3 Structure
The body-centered BaPdSn3 structure contains Sn atoms in tetrahedral and square-pyramidal five-coordinate sites, and Pd in square-pyramidal environments. The PdSn32three-dimensional lattice can be formally decom posed into first two-dimensional layers, then into a square Sn lattice with capping Sn and Pd atoms. This geometrical decom position also serves as a construction principle for building...
