Compared to their solution-state counterparts, solid-state fluorescent photoswitches offer advantages such as enhanced stability and ease of processing/integration, representing a more desirable form for practical applications. However, the restricted molecular packing in the solid state often hinders the photoisomerization of the photochromic units, leading to compromised photochromic performance. The integration of aggregation-induced emission (AIE) motifs with fluorescent photoswitches is an effective strategy for achieving high-performance solid-state fluorescent photoswitches. The twisted conformations of AIE luminogens (AIEgens) provide the necessary spatial freedom for the photoisomerization of the photochromic units in the solid state, thereby successfully overcoming the limitations imposed by molecular packing and enabling efficient solid-state fluorescent photoswitching. This review summarizes the representative types of solid-state fluorescent photoswitchable molecular systems developed in recent years based on this strategy, along with their applications. It aims to provide guidance for the design of novel solid-state photoswitchable systems and is significant for deepening the understanding of their stimulus-responsive mechanisms, developing new materials, and expanding their application scope.</p>","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Activation through the formation of esters gives a characteristically less reactive intermediate in subsequent reactions compared to other related functionalities (e.g. acyl chlorides). Fluorinated ester functional groups offer the ability to significantly modulate the electronics of the system to allow for reactions to occur under mild conditions and hence offer new activation modes starting directly from carboxylic acids.

Particularly, PDT activated or driven by intracellular redox environment attracts increasing attention. In this feature article, we present our efforts on this theme in the past five years, including (1) in-mitochondria synthesis of cyanine-based photosensitizer (PS); (2) glutathione (GSH) participating PS activation via cascade reaction; (3) GSH or 1,4-dihydronicotinamide adenine dinucleotide (NADH) driven reductive PDT (rPDT). Additionally, the emergent concepts, molecular designs and photochemical mechanisms are also discussed in detail. Finally, we provide an outlook on future progression to better meet the clinical applications. We hope that the new perspective on intratumoural redox environment-responsive PDT will inspire the further development of advanced phototherapy like rPDT.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"28 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
