B−N Double Tweezers Comprising Arylboronic Esters and Diamines: Self‐Assembly in Solution and Adaptability as Hosts for Aromatic Guests in the Solid State (ChemPlusChem 4/2020)

Abstract

The Cover Feature shows the self-assembly of arylboronic esters and diamines into 1 : 1 and 2 : 1 boron–nitrogen adducts in solution, and the formation of host–guest complexes with aromatic molecules such as pyrene in the solid state. The rhythm of these processes is dictated by the equilibrium constant K, which determines the proportion of each species in solution. A glimpse of these events in solution was made possible by NMR and UV/Vis spectroscopic studies and the final pictures were taken from single crystal X-ray diffraction analysis. More details can be found in the full paper by H. Höpfl, H. Morales-Rojas, and co-workers on page 548 in Issue 3, 2020 (10.1002/cplu.201900717).
