“…S4 (ESI †). The DSC curves of the pristine crystal of TBM exhibited strong endothermic peak at 151 C, corresponding to its melting point, while other one broad exothermic transition peak appeared at 60 C in the ground powder of TBM, which could be ascribed to the cold-crystallization (crystallizing from glass state) of ground TBM powder upon annealing 26 and also conrmed that the amorphous state was a metastable state. As a result, we deduced that the emitting color changes were due to the transformation between the crystalline and amorphous state.…”

“…The change of MFC mechanism was attributed to the steric effect of tetraphenylethene and long alkyl group, which led to amorphous morphology in the original sample. However, systematic investigation on alkyl length-dependent MFC properties is still a challenging issue due to the following reasons: first, introduction of longer alkyl chains usually increases the steric effect and limits understanding the MFC mechanism through growth of single crystal [7]; second, the previous reported literatures about structural factors like D-A effect and steric effect to regulate the MFC properties are still rare and the mechanism is still unclear [23][24][25]. Therefore, development of novel MFC materials by fine-tuning appropriate D-A effect and steric effect, and to further understand the alkyl length-dependent MFC mechanism is very attractive and highly demanded [26,27].…”
