Covalent organic
WebDynamic covalent chemistry ( DCvC) is a synthetic strategy employed by chemists to make complex supramolecular assemblies from discrete molecular building blocks. [1] DCvC has allowed access to complex assemblies such as covalent organic frameworks, molecular knots, polymers, and novel macrocycles. [2] WebAnswer (1 of 2): Well, hmmm. The question seems to impose a binary choice that doesn’t really exist. Each bond is either covalent or ionic (or shades of grey). And certainly an …
