15 May: DIRECT VISUALIZATION OF PYRROLE REACTIVITY BY CONFINED OXIDATION IN A CYCLODEXTRIN METAL-ORGANIC FRAMEWORK

Alejandro’s work has just been published in Angewandte Chemie Int. Ed. In this paper, Single-Crystal X-Ray Diffraction is used to follow the restricted polymerization of pyrrole inside a cyclodextrin MOF, which generates discrete units of highly reactive cationic terpyrrole inside the pores. This work gives unprecedented information about the host-guest interactions that limit the formation of polymers, that can be useful to future works using MOFs as templates for polymerization processes.

10 Ene: ORIGIN OF THE CHEMIRESISTIVE RESPONSE OF ULTRATHIN FILMS OF CONDUCTIVE METAL–ORGANIC FRAMEWORKS

Víctor, Neyvis and Garin’s work has just been published in Angewandte Chemie Int. Ed. This joint effort shines some light into the underlying mechanism behind the chemiresistive phenomena displayed by electrically conductive MOFs. Taking advantage of our previously reported devices based on Cu-CAT-1 ultrathin films (~30 nm), we used experimental data in combination with computational modelling to obtain evidence for a guest dependent modification of the MOF’s electronic structure. This causes a direct dependence between the electrical response of the MOF and guest interactions with its open metal nodes. You can see the full text here
