Interaction with inorganic molecules

These molecules are set up for supramolecular interactions with inorganic (salts) or organic guests. This concept has been applied to mono- or biphotochromic dihydroindolizines 23 and 31-33.35,36,52-55... 

The interactions of biomolecules with each other and with inorganic molecules and ions. 

Intermolecular interactions between medium-sized systems is a rapidly deevel-oping field of research mainly centering upon molecules of biological interest. The quantum-chemical basis of these interactions with inorganic materials is relatively little explored. The most extensive work is due to Sauer and co-workers, which we will discuss below. Hobza and Zahradnik published an extensive review of nonempirical calculations of weak interaction energies. On the basis of detailed studies they conclude that Hartree-Fock-level ab-initio calculations provide reliable interaction energies, even with the use of limited basis sets, if proper corrections are made for the so-called basis-set superposition error e(BSSE) and the van der Waals interaction is explicitly included ... 

The intermolecular interactions between inorganic molecules can have substantial magnitudes, with both the van der Waals attractions and the coulombic interactions being larger than for organic molecules. 

I S, where neutral template molecules such as amine and block copolymer surfactants interact with inorganic oxide precursors via hydrogen bonds or coordination bonds. 

Inorganic compounds have been used for centuries for their pharmacological properties. Recently, however, the understanding of how inorganic compounds interact with biological molecules has enabled chemists, biologists, and physicians to synthesize and test the medicinal qualities of these compounds in a more systematic way. The unique properties of inorganic compounds enable new mechanisms to be exploited in the treatment of many diseases. 

Abstract - Since cyclodextrin not only interacts with organic and/or inorganic compounds through the hydrophobic cavity but also interacts with water molecules through hydrogen bonding and/or electronic interactions, several types of host (solute)... 

Molecular Interactions. Various polysaccharides readily associate with other substances, including bile acids and cholesterol, proteins, small organic molecules, inorganic salts, and ions. Anionic polysaccharides form salts and chelate complexes with cations some neutral polysaccharides form complexes with inorganic salts and some interactions are stmcture specific. Starch amylose and the linear branches of amylopectin form inclusion complexes with several classes of polar molecules, including fatty acids, glycerides, alcohols, esters, ketones, and iodine/iodide. The absorbed molecule occupies the cavity of the amylose helix, which has the capacity to expand somewhat to accommodate larger molecules. The starch—Hpid complex is important in food systems. Whether similar inclusion complexes can form with any of the dietary fiber components is not known.
