Anion-modulated, highly sensitive supramolecular fluorescence chemosensor for C(70).
نویسندگان
چکیده
A new readily synthesized fluorescent chemosensor, calix[1]pyreno[3]pyrrole, displays excellent affinity with C(70). Anion-induced facile conformational changes and the dynamic nature of the receptor could be an excellent scaffold for sensing electron-deficient guests.

Recently, more and more rhodamine derivatives have been used as fluorophores to construct sensors due to their excellent spectroscopic properties. A rhodamine-based fluorescent and colorimetric Fe(3+) chemosensor 3',6'-bis(ethylamino)-2-acetoxyl-2',7'-dimethyl-spiro[1H-isoindole-1,9'-[9H]xanthen]-3(2H)-one (RAE) was designed and synthesized. Upon the addition of Fe(3+), the dramatic enhancement...
متن کاملA recyclable polyoxometalate-based supramolecular chemosensor for efficient detection of carbon dioxide.
A new type of supramolecular chemosensor based on the polyoxometalate (POM) Na9DyW10O36 (DyW10) and the block copolymer poly(ethylene oxide-b-N,N-dimethylaminoethyl methacrylate) (PEO114-b-PDMAEMA16) is reported. By taking advantage of the CO2 sensitivity of PDMAEMA blocks to protonate the neutral tertiary amino groups, CO2 can induce the electrostatic coassembly of anionic DyW10 with protonate...
