Supramolecular polymerization.

ion of the proton from the amino group of the monomer (phenyl 4-(alkylamino)benzoate) by the base, the reactivity of the phenyl ester moiety is deactivated, which prevents monomers from reacting with each other. The anion produced by proton abstraction from the monomer will only react with initiator, leading to an activated monomer that possesses a more reactive phenyl ester moiety compared to ...

Toward a versatile toolbox for cucurbit[n]uril‐based supramolecular hydrogel networks through in situ polymerization

The success of exploiting cucurbit[n]uril (CB[n])-based molecular recognition in self-assembled systems has sparked a tremendous interest in polymer and materials chemistry. In this study, polymerization in the presence of host-guest complexes is applied as a modular synthetic approach toward a diverse set of CB[8]-based supramolecular hydrogels with desirable properties, such as mechanical str...

Non-equilibrium supramolecular polymerization

Supramolecular polymerization has been traditionally focused on the thermodynamic equilibrium state, where one-dimensional assemblies reside at the global minimum of the Gibbs free energy. The pathway and rate to reach the equilibrium state are irrelevant, and the resulting assemblies remain unchanged over time. In the past decade, the focus has shifted to kinetically trapped (non-dissipative n...

Compression, supramolecular organization and free radical polymerization of ethylene gas

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...
