Lower-rim ferrocenyl substituted calixarenes: new electrochemical sensors for anions
نویسندگان
چکیده
New ferrocene substituted calix[4 and 5]arenes have been prepared and the crystal structure of a lower-rim substituted bis ferrocene calix[4]arene (7) has been elucidated. The respective ferrocene/ferrocenium redox-couples of compounds 6 (a calix[4]arene tetra ferrocene amide) and 8 (a calix[5]arene pentaferrocene amide) are shown to be significantly cathodically perturbed in the presence of anions by up to 160 mV in the presence of dihydrogen phosphate. © 1998 Elsevier Science Ltd.

Lower-Rim Substituted Calixarenes and Their Applications
This review discusses in detail "calixarenes" since their discovery as by-products of the phenol formaldehyde bakelites till the present scenario wherein calixarene has assumed a new dimension in the field of supramolecular chemistry. Extensive literature exists for calixarenes; but herein we have tried to concentrate on the different lower-rim modified calixarenes with their potential applicat...
متن کاملFerrocenyl pyrazaboles: design, synthesis, structure, and properties.
This article reports the design and synthesis of donor-acceptor-donor type ferrocenyl-substituted pyrazaboles by the Pd-catalyzed Suzuki and Sonogashira coupling reactions. The photophysical and electrochemical behaviors of the ferrocenyl-substituted pyrazaboles were found to be dependent on the nature and length of the spacer groups. The single crystal X-ray structures of ferrocenyl-substitute...
متن کاملStructural conditions required for the bridge lithiation and substitution of a basic calix[4]arene
Lithiation and subsequent reaction with CO(2) was applied to calix[4]arenes with different, equal or mixed, ether functions at the lower-rim site as well as tert-butylated or non-tert-butylated upper-rim positions. Whereas this reaction fails for symmetric calix[4]arene ethers with alkoxy residues greater than methoxy, the carboxylation of mixed methoxy-propoxy calixarene ethers is possible. In...
متن کاملPt(II)-activated coupling of aminoethylferrocene with benzonitrile. A facile access route to a new redox-active bis(ferrocenyl-amidine) anion sensor.
A new heterometallic electroactive compound having the ferrocenyl moiety attached to the platinum atom through an amidine functionality has been prepared via Pt(II)-mediated nucleophilic addition of β-aminoethylferrocene to a benzonitrile ligand. This neutral receptor shows remarkable electrochemical anion-sensing redox response to H(2)PO(4)(-).

The readily accessible -chlorophosphonates (OCH2CMe2CH2O)P(O)CH(Cl) C6H4-4-R [1: R=Me (a), OMe (b), Cl (c), H (d)] react with ferrocenecarboxaldehyde in the presence of NaH [Horner–Wadsworth–Emmons reaction] to give good yields of ferrocenyl substituted chlorostilbenes. The novel bis ferrocenyl butadiene C5H5FeC5H4 CH CH C(CN)CHC5H4FeC5H5 (9) as well as the ferrocenyl 2-cyano-1,3-butadienes 4-R...
