Bent-core luminescent and electroactive bis(triazolyl)triazines with compact columnar mesomorphism†
Abstract
The bulk self-assembly of bent-core molecules based on the novel structure 2-methoxy-4,6-bis(1′,2′,3′-triazol-4′-yl)-1,3,5-triazine is reported together with their luminescent and electrochemical properties. Two families of compounds with lateral branches of different lengths have been investigated. Columnar mesomorphism with short stacking distances and periodic twisted structures were found. A compound exhibiting two hexagonal columnar mesophases that show different emission spectra and a transition from a bimolecular assembly to a unimolecular assembly is described.
