Self-Assembly of Arylboronate Esters with Pyridyl Side Chains

Rosario Scopelliti, Kay Severin, Erin Sheepwash, Kai Zhou

Boronate esters that contain N-donor groups are self-complementary structures, which can assemble by means of dative boron–nitrogen bonds to form macrocycles or polymers. Herein, we describe the synthesis of dioxaborinanes and benzodioxaboroles containing ...

Boron-Nitrogen Dative Bonds in Structural Supramolecular Chemistry

Erin Sheepwash

This work describes the use of boron-nitrogen dative bonds in supramolecular chemistry. Molecular tectons have been synthesized for crystal engineering. These tectons are linked via B-N dative bonds to form 1-dimensional polymers and macrocycles. B-N dativ ...

Supramolecular polymers based on dative boron–nitrogen bonds

Kay Severin, Nicolas Luisier, Erin Sheepwash

Heteroditopic monomers containing an arylboronate ester and a dialkyl-4-aminopyridine group aggregate via dative boron–nitrogen bonds to give main chain supramolecular polymers. The degree of polymerization can be tuned by changing the electronic and steri ...

Molecular Networks Based on Dative Boron-Nitrogen Bonds

Rosario Scopelliti, Kay Severin, Erin Sheepwash, Antonia Neels, Olha Sereda, Vincent Krampl

The BN connection: Crystalline and soft molecular networks can be constructed using dative BN bonds (see picture). The networks are obtained in a one-step, three-component reaction involving a triboronic acid, a catechol, and a bipyridyl linker. ...

Dative boron–nitrogen bonds in structural supramolecular chemistry: multicomponent assembly of prismatic organic cages

Rosario Scopelliti, Kay Severin, Kurt Schenk, Erin Sheepwash, Burçak Içli

The multicomponent reaction of diboronic acids with a catechol and a tripyridyl linker results in the formation trigonal prismatic cages. The cages feature six dative boron–nitrogen bonds as structure-directing elements. The size of the cages can be varied ...
