Nonconventional luminogens, represented by clustering-triggered emission (CTE) materials, have attracted increasing attention owing to their unique intrinsic emission and promising applications. However, the influencing factors of clustering-triggered emission and gelation behavior remain poorly understood. Herein, a series of poly(thioether)s with different pendant groups were synthesized and their unique properties were studied. Owing to the similar molecular structure, all five poly(thioether)s exhibited visible photoluminescence, but the intensity varied when the pendant group or solvent changed, which could be attributed to different clustering degree between polymer chains. Moreover, poly(thioether)s with different pendant groups showed the diverse gelation behavior during polymerization process. The impact of pendant group on the clustering-triggered emission property and gelation behavior of poly(thioether) derivatives were investigated in detail, which might be of great fundamental value for the rational design of functional nonconventional luminogens for biological and medical applications.

以簇触发发射（CTE）材料为代表的非常规发光体因其独特的本征发射和广阔的应用前景而受到越来越多的关注。然而，团簇触发发射和凝胶化的影响因素行为仍然知之甚少。在此，合成了一系列具有不同侧基的聚硫醚并研究了它们的独特性能。由于分子结构相似，所有五种聚硫醚均表现出可见光致发光，但当侧基或溶剂变化时，强度有所不同，这可能归因于聚合物链之间的聚集程度不同。此外，具有不同侧基的聚硫醚在聚合过程中表现出不同的凝胶行为。详细研究了侧基对聚硫醚衍生物的团簇触发发光性能和凝胶行为的影响，这对于合理设计用于生物和医学应用的功能性非常规发光体具有重要的基础价值。
