Deslocalización electrónica en cadenas metálicas lineales unidas por sistemas π-conjugados

Abstract

La posibilidad de utilizar moléculas individuales como dispositivos electrónicos autónomos ha supuesto, en los últimos años, un amplio desarrollo de nuevas líneas de investigación. La electrónica molecular plantea el diseño de circuitos en los que algunos de sus elementos constituyentes serían los denominados “cables moleculares”. Dicho término se utiliza para describir moléculas discretas capaces de conectar dos especies de manera que pueda producirse un transporte de carga a través de la molécula.Cadenas metálicas lineales de iridio, comúnmente conocidas como azules de iridio, son candidatas perfectas para dicho fin, ya que permiten la deslocalización electrónica a través de los átomos metálicosque gozande un estado de oxidación formal fraccionario. Sin embargo, la estabilidad de estos sistemas decrece al aumentar la longitud de la cadena, por lo que el diseño de entidades de mayor nuclearidad puede resolverse con el uso de conectores orgánicos. En esta comunicación mostraremos los resultados obtenidos al conectar la cadena tetrametálica[2]de formulación [{Ir2(μ-OPy)2(CH3CN)(CO)4}2](PF6)2 (OPy = 2-piridonato)con sistemas π-conjugados como piridina, pirazina y acetilenos. La figura muestra el resultado de unir dos cadenas tetrametálicas con una unidad fenildiacetiluro que presenta una longitud de unos 3 nm y que presenta una deslocalización electrónica entre los extremos de la cadena.
