Furan-based compounds such as furfural (FF) and 5-hydroxymethylfurfural (HMF) are versatile building blocks for fuels and chemicals. However, their production during pretreatment often suffers from low yield and low separation efficiency. Biphasic solvent systems are capable of reducing biomass recalcitrance and extracting furans into the organic phase, thus preventing their degradation, increasing their yield, and allowing much easier separation. The development of a sustainable biphasic solvent system is essential to the furan-driven biorefinery and has drawn significant attention.

Xanthene-based fluorophores, such as fluorescein and rhodamine, have been in continual use across numerous fields since their invention in the late 19th century. Modern methods to synthesize and expand the scope of xanthene dye chemistry have enabled new colors, enhanced stability, and improved brightness. Modifications to the 3-position of xanthene dyes have been, until recently, less well-explored. Here, we discuss how small changes to the identity of the substituent at the 3-position of fluoresceins and rhodamines can profoundly alter the properties of xanthene dyes, with the potential to unlock new applications at the interface of chemistry and biology.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"10 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140020114","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}
