Synthesis of a Phosphorus-Containing Hybrid Porphyrin
... A phosphorus-containing hybrid porphyrin was successfully prepared via the BF3-promoted dehydrative condensation between σ4phosphatripyrrane and 2,5-bis[hydroxy(phenyl)methyl]thiophene. The NMR and UV−vis absorption spectra, electrochemical measurements, and DFT calculations revealed that the σ3-P,N ...

Equilibrium Part 2
... The ΔH is positive, so the forward reaction is endothermic (we can consider heat to be a reactant in this reaction). According to Le Chatelier’s Principle, adding heat is a stress on a system at equilibrium. The system attempts to remove added heat by using it up in the forward reaction (endothermic ...

Supramolecular catalysis
Supramolecular catalysis is not a well-defined field but it generally refers to an application of supramolecular chemistry, especially molecular recognition and guest binding, toward catalysis. This field was originally inspired by enzymatic system which, unlike classical organic chemistry reactions, utilizes non-covalent interactions such as hydrogen bonding, cation-pi interaction, and hydrophobic forces to dramatically accelerate rate of reaction and/or allow highly selective reactions to occur. Because enzymes are structurally complex and difficult to modify, supramolecular catalysts offer a simpler model for studying factors involved in catalytic efficiency of the enzyme. Another goal that motivates this field is the development of efficient and practical catalysts that may or may not have an enzyme equivalent in nature.A closely related field of study is asymmetric catalysis which requires molecular recognition to differentiate two chiral starting material or chiral transition states and thus it could be categorized as an area of supramolecular catalysis, but supramolecular catalysis however does not necessarily have to involve asymmetric reaction. As there is another Wikipedia article already written about small molecule asymmetric catalysts, this article focuses primarily on large catalytic host molecules. Non-discrete and structurally poorly defined system such as micelle and dendrimers are not included.
