Abstract: Beyond their traditional applications as shape-selective catalysts, selective absorbers and cation exchangers, zeolites – thanks to their structure and chemistry – can be considered as small chemical laboratories, where reactions can be obtained and promoted.
High pressure is an ideal tool for implementing chemical reactions, induced by purely mechanical methods tuning the intermolecular/interatomic distances and leading to a rearrangement of chemical bonds.
ZAPPING project aims to merge the potentialities of high-pressure technologies with microporous materials properties, to induce and control chemical reactions proved effective in driving the formation of arrays with desired dimensionality.
ZAPPING is a challenging interdisciplinary project in which the synergy of the competences of scientists coming from different material science areas (mineralogy, chemistry, physics, computational physical-chemistry, chemical-engineering) will be exploited to gain knowledge on the organization of confined supramolecular nanosystems.
This target represents itself a breakthrough in the field of the synthesis and organization of supramolecular nanosystems, and, most important, will be the foundation for the development of devices for the environmental monitoring and protection.
ZAPPING project will exploit the porous template effectiveness of zeolites in inducing the aggregation and oligomerization/polimerization along preferential directions, not easily achievable under bulk, nor confined conditions.
This will allow the development of functional materials with enhanced functionalities, such as confined polymers with low dimensionality, to be integrated in devices (i.e. gas sensing devices).
Two main systems will be targeted, both based on the exploitation of host zeolites:
i) alkines + zeolite: to promote the polymerization of hydrocarbons to give conductive polymers.
These composite materials will be exploited for environmental purposes, integrating them in gas sensors sensitive to air pollutant like sulfur dioxide, carbon monoxide, nitrogen dioxide, and volatile organic compounds;
ii) unactivated amino acids + zeolite: to induce the condensation of amino acids by a solvent-free, “green” peptide synthesis.
In fact, the formation of amide/peptide bonds in sustainable conditions represents a challenge in the field of the synthesis of fine chemicals in an “atom economy regime”, and will open the way on new synthesis strategies.
Moreover, the investigated process could provide insights useful for shading light on amino acids polymerization under abiotic conditions, which is a still open issue in prebiotic chemistry.
