Crystalline and Soft Materials Based on Dative Boron-Nitrogen Bonds

The thesis describes the utilization of dative boron-nitrogen bond is used for the construction of new materials. In chapter 2.1, the synthesis of new organogels based on bisimidazolyl ligands and diboronate esters is described. Gels with a critical gel co ...

Crystal Engineering of Polymeric Structures with Dative Boron–Nitrogen Bonds: Design Criteria and Limitations

Rosario Scopelliti, Kay Severin, Kurt Schenk, Farzaneh Fadaei Tirani, Philip Pattison, Euro Solari, Nicolas Luisier, Kevin Bally

The combination of tripyridyl ligands and linear diboronate esters results in the formation of oligomeric or polymeric adducts featuring dative boron−nitrogen bonds. The relative orientation of the two different building blocks in the assemblies can be pre ...

Supramolecular gels based on boronate esters and imidazolyl donors

Rosario Scopelliti, Kay Severin, Nicolas Luisier

Dative boron–nitrogen bonds can be used for the controlled assembly of boronate esters and N-donor ligands. So far, most investigations have focused on crystalline assemblies. In contrast, there are very few reports about soft materials based on dative B–N ...

A four-component organogel based on orthogonal chemical interactions

Kay Severin, Kurt Schenk, Nicolas Luisier

A thermoresponsive organogel was obtained by orthogonal assembly of four compounds using dynamic covalent boronate ester and imine bonds, as well as dative boron-nitrogen bonds. It is shown that the gel state can be disrupted or reinforced by chemicals whi ...

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 ...

A ratiometric fluorescence sensor for caffeine

Kay Severin, Anne-Clémence Corminboeuf, Albert Ruggi, Nicolas Luisier, Nicolas David Gaeng, Laurane Favre

The dye disodium 3,4:3’,4’-bibenzo[b]thiophene-2,2’-disulfonate can be used as molecular probe for the fluorimetric detection of caffeine in aqueous solution. The fluorescence response is attributed to non-covalent interactions of caffeine with the dye in ...
