For the melted powders,due to the rapid cooling,the molecules may have quickly aggregated to become amorphous,which tends towards a more planar structure.This proposal was further supported by the poor reflection peaks of the PXRD pattern in Fig. 3B. During the long annealing process (Film-h),the molecules in the powder might restructure themselves andadopt a more distorted conformation to fit into the crystalline lattice, which enables the powder to emit a weak fluorescence.Uniquely, the quantum yields of samples Melted-m and the drop-casting film were evidently higher than that of the ground powder, which could be attributed to the uneven grinding force applied to the pristine powder and the spontaneous recovery ability of the ground powder. As depicted in Fig. S7,† the
emission intensity of the freshly ground powder was spontaneously reduced with a slight blue-shift as time passed. Thus,the obtained quantum yields become smaller. In a word, the solid-state TPA-CO with larger twist angles exhibited a tunable molecular conformation, which led to a change in intramolecular conjugation and intermolecular interactions under external stimuli.

對于熔融的粉末，由于快速冷卻時(shí)分子可能很快聚集成為無定形的狀態(tài)，這往往趨于形成一平面結(jié)構(gòu)。這一設(shè)想得到了圖3B的支持：在PXRD圖譜中，反射峰很差。在漫長的退火工藝（Film-h）中，粉末中的分子可能轉(zhuǎn)型，并采用更扭曲構(gòu)象裝配到結(jié)晶晶格，從而使該粉末發(fā)出微弱的熒光。很獨(dú)特的是，樣品的量子產(chǎn)率Melted-m和滴流延制膜均明顯高于研磨的粉末，這可能是由于施加到原始粉末的研磨力不均勻以及研磨粉末的自發(fā)恢復(fù)能力。如圖S7†所示，新鮮磨碎粉末的發(fā)光強(qiáng)度隨著時(shí)間的流逝被自發(fā)地減弱，并出現(xiàn)輕微的藍(lán)移。因此，所獲得的量子產(chǎn)率變小�？傊�，具有較大扭轉(zhuǎn)角的固態(tài)TPA-CO具有一種可調(diào)的分子構(gòu)象，在外部刺激作用下可以導(dǎo)致分子內(nèi)部交聯(lián)以及分子之間的相互作用。
