detección de pesticidas, fluorescencia, MOF, Zn(II)Resumen
La aplicación extensa de pesticidas y herbicidas en los sectores agrícola y doméstico exige un avance continuo en las tecnologías de su detección y monitoreo. Dada la amenaza ambiental y sanitaria que representa la bioacumulación de estas especies tóxicas en fuentes hídricas, alimentos y suelos, existe una necesidad imperativa y creciente de desarrollar métodos de detección en tiempo real, que sean económicos, precisos y que operen eficientemente en muestras ambientales complejas. En los últimos años, el uso de redes metalorgánicas (mof) luminiscentes en su aplicación como sensores de contaminantes del agua ha brindado resultados prometedores, como una alternativa eficiente, selectiva, económica y reproducible para el monitoreo de sustancias tóxicas en cuerpos acuáticos. Particularmente, los mof basados en Zn(II) destacan debido a su estructura robusta, propiedades luminiscentes y prometedora biocompatibilidad en la detección óptica de agroquímicos nocivos. Estos materiales quimiosensores fundamentan su mecanismo de respuesta en procesos primarios de transferencia de carga y emisión intraligante. Esta capacidad permite el análisis cuantitativo de contaminantes peligrosos mediante la medición de sus propiedades de luminiscencia en tiempo real. Por consiguiente, en el presente artículo se destacan ejemplos recientes que ilustran el diseño estructural y as capacidades de reconocimiento selectivo y respuesta fluorescente de estos arreglos de coordinación cristalinos basados en Zn(II), para la cuantificación directa y precisa de pesticidas y herbicidas de uso común en muestras reales de sistemas acuáticos.
