“…We also note a fluorescein-appended β-cyclodextrin 254a which may show related effects when its guest responsive fluorescence is examined. The fluorescence response of nonmacrocyclic but internally hydrogen bonded 48 to high concentrations of Li + in acetonitrile has some similarities to the Mg 2+ -binding 1,8-dihydroxyanthraquinone mentioned previously …”

“…The TICT fluorophore shows considerable enhancement of emission along with a significant blue-shift useful for ratiometry. The Zn(II) response of this supramolecular system compares very well with that of the more classically designed sensor 98 , of the ICT type which has much in common with 8-hydroxyquinoline and others discussed earlier. − …”

“…Prior to this benevolent invasion of biology by molecular fluorescent sensors/switches, there were examples quietly serving analytical chemistry. 8-Hydroxyquinoline, 2,2‘-dihydroxyazobenzene, and 1,8-dihydroxyanthraquinone are classical Mg 2+ reagents of this type. The growing influence of macrocyclic systems broke into the field of fluorescent sensors with two studies on dibenzo-18-crown-6 ether. , More highly functionalized macrocyclic sensors 28 , and 29 were also in the vanguard.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
