“…A rhodamine‐based dual signalling compound 36 was synthesised for the optical detection of Hg 2+ ions . The compound displayed a 252‐fold enhancement in the fluorescence at 553 nm in presence of Hg 2+ ion; and the enhancement was completely reversible upon treating the compound 36 :Hg 2+ complex with I − ions (Figure ).…”

“…In addition, the challenging task of monitoring the intracellular Ca 2+ ion concentration could be effectively executed with the Ca 2+ ‐ion detectable organic molecules . A variety of organic sensors are available for the detection and quantification of Hg 2+ ions; these sytems can, in turn, be developed as devices for the selective detection of Hg 2+ ions.…”

Computers have become smarter, smaller, and more efficient due to the downscaling of silicon-based components. Top-down miniaturisation of silicon-based computer components is fast reaching its limitations because of physical constraints and economical non-feasibility. Therefore, the possibility of a bottom-up approach that uses molecules to build nano-sized devices has been initiated. As a result, molecular logic gates based on chemical inputs and measurable optical outputs have captured significant attention very recently. In addition, it would be interesting if such molecular logic gates could be developed by making use of ion sensors, which can give significantly sensitive output information. This review provides a brief introduction to anion receptors, molecular logic gates, a comprehensive review on describing recent advances and progress on development of ion receptors for molecular logic gates, and a brief idea about the application of molecular logic gates.

Optical sensor: a promising strategy for environmental and biomedical monitoring of ionic species

There is fast growing research on designing and improving the metal recognition methodologies in the ecosystems and biological media. The fluorescent based techniques proved a mile stones for non-invasive metal sensation and quantification in the multichannel environment. Metals as the natural components of Earth's crust are generally present in trace concentrations in the environmental samples where the humic substances have complexation affinity toward them. Iron, zinc and copper are the 1 st , 2 nd and 3 rd adequate elements indispensable to the body in trace playing the crucial roles in many biological processes. However, the unregulated amounts either as excess or deficient may exacerbate deterioration to the vital organs and triggered the progression of complications. Beside these three essential elements, mercury is widely considered to be one of the most hazardous pollutants and highly dangerous elements due to its recognized accumulative and toxic characters in the environment and the ecosystem. In the current scenario, we have tried to summarize the maximum amount of recently developed fluorescent signaling materials for the Cu 2+ , Fe 2+ / Fe 3+ , Zn 2+ and Hg 2+ . The spectral shifting in the molecules on metal chelation, mode of complexation and stoichiometries of resulting adducts have been discussed in detail. Furthermore, the molecules which have been reported as intracellular metal detector via bioimaging are specifically highlighted that might be useful for the design and development of cell viable and membrane permeable molecular probes in the future perspective.

“…Another example is for Hg 2+ sensing via the use of the rhodamine-based chemosensor 20 reported by Ali group (Figure 15). 46 The formation of 1:1 coordination metal complexes is signalled by both colorimetric and fluorogenic changes in organic-water mixtures. In addition, the reversible binding of 20 with Hg 2+ by addition of KI offered the potential design of INHIBIT logic devices.…”

P."En algún sitio algo increíble espera ser descubierto. Somos polvo de estrellas que piensa acerca de las estrellas" Carl Sagan Acknowledgements AgradecimientosPara comenzar quiero agradecer a mis directores de tesis Ramón Martínez y Félix Sancenón, no tan solo por su siempre cordial ayuda y sabio consejo, sino también por brindarme la oportunidad de trabajar estos años bajo su tutela y depositar en mi su confianza al recibirme en su grupo de investigación. Muchas gracias por su guía y aun más por su amistad.Gracias también a un grupo especial de profesores que me brindaron en muchas ocasiones su incondicional ayuda profesional y personal y cuyas conversaciones y consejos han enriquecido mi vida en estos años.Muchas gracias a vosotros Juan Soto, Dolores Marcos, Luis Villaescusa, José Vicente Ros, Salvador Gil y Knut Rurack.Mil gracias a todos mis compañeros y colegas que durante estos años me han brindado su incondicional apoyo, ayuda y motivación para seguir adelante y que han hecho de mi estancia en tierras europeas una de las mejores etapas de mi vida. No me bastarían las líneas para expresarles cuanto valoro el haberles conocido y poder nombrarles ahora entre mis buenos amigos. Tan seguro estoy de su amistad que se de hecho, que aun sin nombrarles ya os sabeis aludidos. Gracias por los buenos momentos vividos dentro y fuera de la universidad, sois parte de mis mejores recuerdos y lo mejor de esta etapa.Gracias también a mis hermanos y mis padres por ser siempre una pieza clave de mi soporte en la vida y ofrecerme aun a la distancia la calidez de su compañía. Nada hubiese sido posible sin vuestro apoyo.Gracias a ti mi amada esposa, por ser desde hace mucho mi compañía en cada paso. Gracias por alegrar mi vida y hacer que todos los esfuerzos tengan un verdadero significado.Finalmente, gracias a Dios por todas las bendiciones que me han acompañado en esta etapa de mi vida, en particular por reunir en mí camino a las mejores personas de cuatro diferentes continentes. Soc. Rev., 2013, 42, 3489-3613). Esta revisión bibliográfica, si bien no ha sido incluida explícitamente en esta tesis doctoral debido a su larga extensión, constituye sin lugar a duda, parte del sustento teórico del trabajo experimental que está expuesto en ella, por lo que es citado continuamente como referencia bibliográfica.El trabajo de tesis doctoral está estructurado en cuatro capítulos. El primero de ellos constituye una introducción general que resume los fundamentos teóricos de la química supramolecular en que se basan los estudios prácticos realizados. Los siguientes tres capítulos condensan los principales resultados de la etapa experimental de esta tesis. El orden en que son presentados sigue un esquema lógico que favorece su mejor comprensión en conjunto y no una distribución temporal del momento en que fueron realizados.El capítulo dos está dedicado a la síntesis, caracteriza...
