Anion binding vs. deprotonation in colorimetric pyrrolylamidothiourea based anion sensors.
نویسندگان
چکیده
A pyrrolylamidothiourea deprotonates in the presence of one equivalent of not only fluoride, but also acetate, benzoate or dihydrogen phosphate in DMSO solution with structural studies using synchrotron radiation confirming thiourea deprotonation in the solid state.

Indoles and Related Heterocycles
Indole and the related heterocycles have emerged as efficient building blocks for the creation of novel anion receptors. This chapter focuses on the employment of indoles, carbazoles, and indolocarbazoles in the creation of molecular clefts, macrocycles, oligomers, and sensors. The majority of these structures utilize the heterocyclic NH as a hydrogen bond donor in binding to anions of various ...

Molecular sensors able to detect ions are of interest due to their potential application in areas such as pollutant sequestration. Alkynylplatinum(II) terpyridine complexes with an amide-based receptor moiety have been synthesized and characterized. Their anion binding properties based on host-guest interactions have been examined with the use of UV-vis absorption and emission spectral titratio...
متن کاملA Dual colorimetric and Fluorometric Anion Sensor Based on Polymerizable 1, 8-Naphthalimide Dye
A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...
متن کاملTriarylborane conjugated dicyanovinyl chromophores: intriguing optical properties and colorimetric anion discrimination.
Three new triarylborane conjugated dicyanovinyl chromophores (Mes2B-π-donor-DCV); donor: N-methyldiphenylamine () and triphenylamine ( and [with two BMes2 substitutions]) of type A-D-A (acceptor-donor-acceptor) are reported. Compounds exhibit intense charge transfer (CT) absorption bands in the visible region. These absorption peaks are combination CT bands of the amine donor to both the BMes2 ...
