Systems chemical analytics: introduction to the challenges of chemical complexity analysis
2019
Understanding complex (bio/geo)systems is a pivotal challenge in modern sciences that fuels a constant development of modern analytical technology, finding innovative solutions to resolve and analyse. In this introductory paper to the Faraday Discussion "Challenges in the analysis of complex natural systems", we aim to present concepts of complexity, and complex chemistry in systems subjected to biotic and abiotic transformations, and introduce the analytical possibilities to disentangle chemical complexity into its elementary parts (i.e. compositional and structural resolution) as a global integrated approach termed systems chemical analytics.
Exploring chemical complexity in group IV reticular solids
2022
Esta tesis aborda el reto de ampliar las herramientas sintéticas disponibles para aumentar la complejidad química de los materiales reticulares basados en metales del grupo IV, dirigiéndose tanto a la parte orgánica como a la inorgánica de estos materiales porosos e híbridos. El capítulo 1 ofrece una visión del aumento de la complejidad química en los sólidos reticulares, que proporciona un contexto general a los resultados desarrollados durante esta tesis. A continuación, la introducción de la variación química en los conectores orgánicos se describe en los capítulos 2, 3 y 4, mientras que la transformación química de los nodos inorgánicos se introduce en el capítulo 5. Todo el trabajo des…
Perceptual odor blending is influenced by chemical complexity of odorant mixtures
2008
International audience; Perfumers and flavorists are familiar with odor blending phenomenon and often report that a minimum number of odorants has to be mixed for a good odor blend to arise. Previous studies in humans and animals suggested that a configural process could be involved in the perceptual analysis of mixtures of odorants. It has been proposed that the perceptual blending phenomenon corresponds to a configural perception of odorant mixtures. In the present study, we investigated the influence of chemical complexity on the configural perception of odorant mixtures. Six mixtures including 2 to 6 odorants as well as each unmixed odorant were assessed for their odor quality by a pane…
Strategies for Exploring Functions from Dynamic Combinatorial Libraries
2020
Dynamic combinatorial chemistry (DCC) is a powerful approach for creating complex chemical systems, giving access to the studies of complexity and exploration of functionality in synthetic systems. However, compared with more advanced living systems, the man‐made chemical systems are still less functional, due to their limited complexity and insufficient kinetic control. Here we start by introducing strategies to enrich the complexity of dynamic combinatorial libraries (DCLs) for exploiting unexpected functions by increasing the species of building blocks and/or templates used. Then, we discuss how dynamic isomerization of photo‐switchable molecules help DCLs increase and alter the systemic…
