Although the traditional treatment is still the mainstream in clinical practice, the emerging phototheranostics technologies based on photoacoustic or fluorescence imaging–guided phototherapy also provide a new exploration direction for the non-invasive, low-risk and highly efficient cancer treatment. Photosensitizer is the core material to accomplish this mission. Recently, more attention has been paid to the emerging A−D−A fused-ring photosensitizers. A−D−A fused-ring photosensitizers display strong and wide absorption spectra, high photostability and easy molecular modification. Since such kind of photosensitizers was firstly used for tumor therapy in 2019, their application boundaries are constantly expanding. Therefore, in this feature article, from the perspective of molecular design, we focused on the development of these molecules in phototheranostics over the past five years. The effects of tiny structural changes on their photophysical properties are discussed in detail, which provides a way for structural optimization of the subsequent A−D−A photosensitizers.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141602675","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}

Additionally, hydrogen-bonded organic frameworks (HOFs), constructed from organic molecules with complementary hydrogen-bonding patterns, are rapidly evolving into a novel category of porous materials due to their facile mild preparation conditions, solution processability, easy regeneration capability, and excellent biocompatibility. These distinctive advantages have garnered significant attention across diverse fields. Given that many MOF linkers can serve as building blocks for constructing HOFs and considering the inherent binding affinity between MOFs and HOFs, their combination holds promise in creating functional materials with enhanced performance. This feature paper provides an introduction to the interconversion between MOFs and HOFs followed by highlighting the emerging applications of MOF/HOF composites. Finally, we briefly discuss the current challenges associated with future perspectives on MOF/HOF composites.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141597245","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}
