“…It has been demonstrated that the receptor can bind anions in a 1:1 stoichiometry (except for F -) with obvious colorimetric changes, where the complex had been formed between 1 and AcO -by hydrogen bonding as proved by 1 H NMR titration. …”

Um receptor para reconhecimento de ânions derivado da tiouréia foi sintetizado combinandose indolina-2,3-diona e 1,3-diaminotiouréia. A interação pode ser facilmente monitorada acompanhando-se as mudanças no espectro de absorção na região do UV-vis induzidas pela complexação de um dado ânion. Por exemplo, verificou-se que o fluoreto liga-se ao receptor na proporção de 1:2, mas esta muda para 1:1 no caso dos ânions di-hidrogenofosfato e acetato. Este último apresenta a maior constante de afinidade dentre eles indicando um melhor reconhecimento molecular pelo novo receptor. Finalmente, a natureza da interação entre o novo receptor e o ânion acetato foram explorados utilizando-se espectroscopia de 1 H-RMN.An anion recognition receptor, a kind of thiourea derivative, was designed and synthesized by combining indoline-2,3-dione and 1,3-diaminothiourea. The anion recognition can be easily monitored by anion complexation induced changes in UV-vis absorption spectra. In particular, the binding ratio between the receptor and fluoride is 1:2 but in the case of dihydrogenphosphate and acetate are 1:1. Moreover, the affinity constants revealed that the receptor can recognize acetate well. Finally, 1 H NMR experiments were carried out to explore the nature of interaction between this new receptor and acetate.

“…For example, Lees previously synthesized a luminescent metal complex integrated with an amide moiety, which exhibited high affinities for cyanide, halides and acetate anions with binding constants as high as 10 4 e10 5 M À1 in CH 2 Cl 2 solution [25]. Chen and Huang designed the novel upper-rim anthracene bridged calix [4] arene and found that the fluorescence of the anthracene group was quenched upon addition of basic anions such as AcO À and F À in acetonitrile solution [26]. Eichen investigated the molecular recognition properties of Cyclo [2]benzimidazole containing two amide groups with fluoride, bifluoride and the oxo anions dihydrophosphate and benzoate through the inhibition of an excitedstate intramolecular proton transfer process [27].…”

“…[1] For the realization of PET mechanism in such sensors, the initial macrocyclic platform of (thia) calix [4]arene is usually modified by reagents with condensed systems (anthranyl, naphthyl fragments) having electron acceptor atoms such as N or O. [4][5][6] It should be noted that often in such fluorescent probes, differently substituted thiacalix [4]arene derivatives in which fluorescent markers as well as different functional groups which confers additional properties on the macrocycle, are employed.…”
