Abstract: The development of molecular machines has long been a dream of scientists and is expected to revolutionize many aspects of technology and medicine. As the prerequisite of a practicable molecular machine, studies on the solid-state molecular motion (SSMM) are not only of scientific importance but also practically useful. Herein, two nonconjugated molecules, 1,2-diphenylethane (

Abstract: Interfaces exist in almost all objects and processes. Investigation on the interface not only is fundamentally important but also has great application prospects. Traditionally, the interface structure is studied by electron microscopy, which cannot reflect its real structure considering the pretreated process before measurement. Monitoring the interface evolution process by these regular methods is time-consuming and unfeasible in many cases. In this perspective article, we discuss how to realize the visualizing and monitoring interface structures and dynamics by aggregation-induced emission technique, which is applicable to almost all kinds of interfaces, including gas-solid, liquid-solid, solid-solid, gas-liquid-solid, and liquid-liquid-solid. Meanwhile, it is anticipated that the circularly polarized luminescence property in prochiral aggregation-induced emission luminogens can make a great difference in this area.

Abstract: Due to the fast dynamics and re‐equilibration of supramolecular self‐assembly, bottom‐up molecular strategies to fabricate well‐defined and controllable multiblock structures are rare. Herein, we propose a new concept for fabrication of fluorescent multiblock microcolumns containing 1 to 7 blocks via hierarchical supramolecular self‐assembly based on cucurbit[8]uril (CB[8]), NaBr and an AIEgen guest. Through the complexation between CB[8] and different numbers of AIEgen guests (2, 1, 0), the competitive displacement caused by the binding of the sodium cation to the CB[8] portal, and the reversible assembly of positively charged guests in salt solutions, one‐pot hierarchical supramolecular self‐assembly is realized. The molecular structure of each block is analyzed by single‐crystal X‐ray diffraction. The AIEgen enables the self‐assembly of multiblocks to be visualized, understood, and regulated.
