•We summarized the state-of-the-art in coordination polymers containing nucleobases.•A collection of structures and properties of these novel materials.•Perspectives for this field in the frontier ...between the coordination chemistry and materials science are pointed out.
This review article focuses on the current state-of-the-art of coordination polymers using nucleobases as ligands. It collects the literature already published in a comprehensive way and attempts to provide perspectives for this research field. The article integrates two important concepts of coordination chemistry, metal–nucleobase chemistry and coordination polymers. It tries to demonstrate novel opportunities for these coordination polymers in terms of architectures and potential applications. The text is presented in three general sections according to the dimensionality of the coordination polymer, and then is subdivided in sections that take into account the structural role of the nucleobase as ligand (either terminal or bridging), and the nature of the nucleobase (pyrimidine vs purine). Synthetic, structural aspects and physico-chemical properties are presented for each sample. Valuable potential applications and perspectives for these novel materials are also discussed.

This work is focused on the chemistry and physical properties of a particular family of coordination polymers (CPs) based on copper-iodine chains bearing functionalized pyridine, pyrimidine and pyrazine ligands. Although this family of compounds has been well-described, most of the studies have been focused on structural characterization and optical properties in bulk scale while works rationalizing their stimuli-responsive behavior and the role of these materials at the nanoscale are being reported very rencently. This article describes the first works in these fields and the perspectives that nanoscaled CPs based on Cu(I)-halide will have in the near future. Thus, the aim of this review is to present the new perspectives that are opening for these materials by deepening in their behavior, considering theoretical calculations, size-dependent properties or their combination with other components to form new hybrid materials. The combination of all these aspects will allow the discovery of interesting materials useful in sensing, nanochips or packaging, among other uses.

This review is an attempt to illustrate the different alternatives in the field of 2D materials. Graphene seems to be just the tip of the iceberg and we show how the discovery of alternative 2D ...materials is starting to show the rest of this iceberg. The review comprises the current state-of-the-art of the vast literature in concepts and methods already known for isolation and characterization of graphene, and rationalizes the quite disperse literature in other 2D materials such as metal oxides, hydroxides and chalcogenides, and metal-organic frameworks.
Este artículo examina la relación entre los conceptos de reconstrucción y ruina durante el primer franquismo a través del análisis de la primera "Exposición de la reconstrucción en Madrid" y la ...maqueta del Alcázar de Toledo en ruinas, ambas de 1940. Este artículo explora cómo las estrategias visuales utilizadas en la exposición y la conformación visual de una imagen de la ruina se utilizaron para transmitir los mensajes ideológicos del régimen. La exposición fue la primera muestra de una selección de planes para la reconstrucción de España tras la guerra, fue diseñada por un equipo de jóvenes arquitectos asociados a la Falange y representa una propuesta clave para pensar la relación entre ideas de tradición y revolución tras 1939. Por el contrario, la imagen del Alcázar como ruina se articuló dentro de los parámetros del nacionalcatolicismo, lo que se tradujo en una versión del asedio de connotaciones religiosas que resaltaba su asociación con el imperio español y la tradición nacional. El régimen transformó el edificio en una ruina capaz de producir legitimidad histórica a través de medios visuales. En última instancia, este artículo sostiene que la tensión entre la reconstrucción y la ruina dio forma a la historicidad del discurso visual del régimen. Como resultado, este artículo nos invita a considerar la posguerra como una temporalidad compleja en la que el pasado, el presente y el futuro estaban entrelazados, y en la que la tradición y la revolución no se veían plenamente como opuestos, sino como aspectos complementarios de la nueva España fascista.
