Dynamic bonds chemistry

WebNew discoveries in ‘dynamic bonds’ could reshape our fundamental understanding of … Dynamic covalent chemistry (DCvC) is a synthetic strategy employed by chemists to make complex supramolecular assemblies from discrete molecular building blocks. DCvC has allowed access to complex assemblies such as covalent organic frameworks, molecular knots, polymers, and novel macrocycles. … See more Dynamic systems are collections of discrete molecular components that can reversibly assemble and disassemble. Systems may include multiple interacting species leading to competing reactions. See more Reactions used in DCvC must generate thermodynamically stable products to overcome the entropic cost of self-assembly. The reactions must form covalent linkages between building blocks. Finally, all possible intermediates must be reversible, and the … See more • Organic chemistry • Supramolecular chemistry • Template effect See more In dynamic reaction mixtures, multiple products exist in equilibrium. Reversible assembly of molecular components generates products and semi-stable intermediates. … See more The concept of a thermodynamic template is demonstrated in scheme 1. A thermodynamic template is a reagent that can stabilize the form of one product over others by lowering … See more Dynamic covalent chemistry has allowed access to a wide variety of supramolecular structures. Using the above reactions to link molecular fragments, higher order materials have … See more
