Multi-stimuli-responsive behaviours of fluorenone-based donor–acceptor–donor triads in solution and supramolecular gel states

Abstract

Bilaterally asymmetric and symmetrical fluorenone-based donor-acceptor-donor (D–A–D) triads bearing hydrogen-bonded urethane units were synthesised in this study. Both the fluorenone derivatives exhibited supramolecular gelation in organic solvents. The bilaterally asymmetrical...
