Fluoride Anion Recognition by a Multifunctional Urea Derivative: An Experimental and Theoretical Study

Schiller, Jana; Pérez-Ruiz, Raúl; Sampedro, Diego; Marqués-López, Eugenia; Herrera, Raquel P.; Díaz Díaz, David (MDPI AG, 2016-05)

[EN] In this work we demonstrate the ability of a multifaceted N,N '-disubstituted urea to selectively recognize fluoride anion (F-) among other halides. This additional function is now added to its already reported ...
Selective and Sensitive Chromogenic Detection of Cyanide and HCN in Solution and in Gas Phase

Gotor Candel, Raul Jesús; Costero Nieto, Ana María; Gil Grau, Salvador; Parra Álvarez, Margarita; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Gaviña Costero, Pablo (Royal Society of Chemistry, 2013-06-25)

Two triphenylmethane based chemodosimeters for selective and chromogenic sensing of cyanide anions in aqueous environments and of hydrogen cyanide in gas phase were prepared and studied.
Synthesis and evaluation of fluorimetric and colorimetric chemosensors for anions based on (oligo) thienyl-thiosemicarbazones

Santos Figueroa, Luis Enrique; Moragues Pons, María Esperanza; Marques Raposo, Maria Manuela; Batista, Rosa M. F.; Ferreira, R. Cristina M.; Costa, Susana P. G.; Sancenón Galarza, Félix; Martínez Mañez, Ramón; Soto Camino, Juan; Ros-Lis, José Vicente (Elsevier, 2012-09-02)

A family of heterocyclic thiosemicarbazone dyes (3a-d) containing thienyl groups has been synthesized, characterized, and their chromo-fluorogenic response in acetonitrile in the presence of selected anions was studied. ...
Synthesis and evaluation of the chromo-fluorogenic recognition ability of imidazoquinoline derivatives toward ions

Marín Hernández, Cristina; Santos, Luis E.; El Sayed Shehata Nasr, Sameh; Pardo Vicente, María Teresa; Raposo, M. Manuela M.; Batista, Rosa M. F.; Costa, Susana P. G.; Sancenón Galarza, Félix; Martínez-Máñez, Ramón (Elsevier, 2015-11)

[EN] Four imidazoquinolines functionalized with different carbocycles and heterocycles were synthesized and characterized. Acetonitrile solns. of the four receptors presented absorption bands in the 330-370 nm range. The ...
Synthesis and evaluation of thiosemicarbazones functionalized with furylmoieties as new chemosensors for anion recognition

Santos Figueroa, Luis Enrique; Moragues Pons, María Esperanza; Raposo, M. Manuela M.; Batista, Rosa M.F.; Costa, Susana P. G.; Ferreira, R. Cristina M.; Sancenón Galarza, Félix; Martínez Mañez, Ramón; Ros-Lis, José Vicente; Soto Camino, Juan (Royal Society of Chemistry, 2012-07-24)

A family of heterocyclic thiosemicarbazone dyes (3a-f and 4) containing furyl groups was synthesized in good yields, characterized and their response in acetonitrile in the presence of selected anions was studied. Acetonitrile ...
Synthesis of a new tripodal chemosensor based on 2,4,6-triethyl-1,3,5-trimethylbencene scaffolding bearing thiourea and fluorescein for the chromo-fluorogenic detection of anions

Moragues Pons, María Esperanza; Santos Figueroa, Luis Enrique; Ábalos Aguado, Tatiana; Sancenón Galarza, Félix; Martínez Mañez, Ramón (Elsevier, 2012-09-19)

A tripodal receptor containing thiourea as binding site and fluorescein as signalling subunit has been designed, synthesized and used for the colorimetric detection of basic anions in DMSO solutions. (C) 2012 Elsevier Ltd. ...
