Perylene diimides (PDI) are a well-studied class of functional organic dyes, and in recent years, they have been accepted as promising scaffolds for the design of small molecule/polymer-based chromogenic and fluorogenic reaction-based-probes because of their strong absorption combined with high fluorescence quantum yield in organic solvents, low reduction potential, good electron-acceptor properties, and broad color range properties. Undoubtedly, the intrinsically poor solubility of PDI-based derivatives in water greatly hampers their exploitation as reaction-based probes; however, a vast array of functionalizations now offer design strategies that have resulted in >50% solubility of PDI derivatives in water. A chemodosimeter, wherein chemical transformation is achieved by specific reactions, affords naked-eye visibility, fast response time, sensitivity, ratiometric response, and low cost. The present review focuses on the progress of PDI-based chemodosimeters achieved so far since the inception of this member in the rylene diimide family. This comprehensive review may facilitate the development of more powerful chemodosimeters based on PDI for broad and exciting applications in the future.

ylene二酰亚胺：它们会作为基于反应的探针发扬光大吗？

ylene二酰亚胺（PDI）是一类经过广泛研究的功能性有机染料，近年来，由于它们的强力作用，它们被认为是用于设计基于小分子/聚合物的发色和基于荧光反应的探针的有前途的支架吸收与有机溶剂中的高荧光量子产率，低还原电位，良好的电子受体性能和宽色域性能相结合。毫无疑问，基于PDI的衍生物在水中的固有差的溶解性极大地阻碍了它们作为基于反应的探针的开发。然而，现在大量的功能化提供了设计策略，这些策略导致PDI衍生物在水中的溶解度> 50％。化学光度计通过特定的反应完成化学转化，提供肉眼可见性，快速响应时间，灵敏度，比例响应和低成本。本综述着重介绍自Rylene二酰亚胺家族中该成员诞生以来到目前为止基于PDI的化学计量仪的进展。这项全面的审查可能会促进基于PDI的功能更强大的化学计量仪的开发，以供将来广泛而令人兴奋的应用。
