Organic molecules with an aggregation-induced emission (AIE) effect have recently been attracting more and more attention due to their colossal potential in solid emitters and chemo/biosensors. The number and variety of AIEgen compounds are expanding very rapidly to obtain better application performance and a wider area of application. Among AIEgen systems, tetraphenylethylene (TPE) and its derivatives are the class that have received the most extensive study and the most rapid development because of their facile synthesis. Due to its C2 symmetry and at least tetratopic reaction positions, the TPE unit is also an ideal building block for constructing macrocycles and cages. The resultant cyclic TPE compounds have exhibited many exceptional performances that are difficult to access in their open chain counterparts, such as AIE enhancement, improvement in selectivity and sensitivity as sensors, emission tuning by guests, supramolecular catalysis, further disclosure of the AIE mechanism, molecular adsorption, storage and release, the propeller-like conformation exploitation of the TPE unit in chiral materials and so on. Recently, therefore, a large variety of studies about the synthesis, properties and application research of TPE macrocycles and cages have been reported. These TPE macrocycles and cages significantly expand the research area for the AIE phenomenon and its applications, and represent a development of the AIE area. However, up to now, no review of TPE macrocycles and cages has been available. Thus, this review serves as a summary of the designs, synthesis, photophysical properties, self-assembly, applications and prospects of TPE macrocycles and cages.

基于四苯乙烯的大环和笼子，具有聚集诱导的发射效应
具有聚集诱导发射（AIE）效应的有机分子由于其在固体发射体和化学/生物传感器中的巨大潜力，最近引起了越来越多的关注。AIEgen化合物的数量和种类正在迅速扩大，以获得更好的应用性能和更广阔的应用领域。在AIEgen系统中，四苯乙烯（TPE）及其衍生物由于易于合成而受到了最广泛的研究和最快的发展。由于其C 2对称性和至少四位反应位置，TPE单元还是构建大环化合物和笼子的理想构建基块。所得的环状TPE化合物表现出许多出色的性能，这些性能在其开链对应物中是难以获得的，例如AIE增强，作为传感器的选择性和灵敏度的提高，客体的发射调谐，超分子催化，AIE机理的进一步公开，分子吸附，储存和释放，手性材料中TPE单元的螺旋桨状构象开发等。因此，最近，已经报道了关于TPE大环和笼的合成，性质和应用研究的各种各样的研究。这些TPE大环和笼子极大地扩展了AIE现象及其应用的研究领域，并代表了AIE领域的发展。但是，到目前为止，还没有关于TPE大环和笼的综述。因此，本综述总结了TPE大环和笼的设计，合成，光物理性质，自组装，应用和前景。
