| Thus, the repulsive force was sufficient to block intermolecular excitonic coupling,which caused fluorescence quenching.Fusing all the results together enabled us to draw a clear overall picture for stimuli-responsive behaviours, as depicted in Fig. 6. In the crystalline state, the luminogens may adopt a more twisted conformation in order to fit into the crystalline lattice. Thus, the pristine crystals exhibit a faint luminescence. Upon amorphization by mechanical force,the molecular structure slightly turned planar and the effective intramolecular conjugation was increased, which significantly blocked the non-radiative deactivation pathways. Also, the neighbouring molecules did not get close to one another due to mutually repulsive dipole interactions, which weakened the intermolecular interactions.As a result,the luminescence of ground powders was turned ¡°bright¡±.The luminescence on-off switching was mainly attributed to the synergy between the planarization of the twisted conformation and weak intermolecular interactions. |
