materiales supramoleculares funcionales ha recibido creciente atención en los
últimos años. Entre ellos uno de los grupos con mayor crecimiento es el de los
geles. Este tipo de material tiene potencial aplicación en la producción de
nanometariales como sensores, electrónica molecular, catálisis, y otras áreas.<sup>1</sup>
Uno de los grupos de moléculas gelificantes de bajo peso molecular más
interesantes es el de moléculas ALE conteniendo grupos
aromático-espaciador(linker)-esteroide (ó ALS del Inglés
aromatic-linker-steroid) en los cuales el grupo esteroidal mas comúnmente
utilizado es colesterol. En este seminario se describirá la síntesis y el
estudio de las propiedades de una nueva familia de organogelificantes
esteroidales derivada de <b>OG1</b> y su uso como molde molecular para la
polimerización de materiales inorgánicos con el fin de obtener nanopartículas
inorgánicas híbridas.<sup>2</sup><o:p></o:p></span></p>
