Self-Assembly of Bio-Nanochips

Final Activity Report Summary - BIO-NCHIPS (Self-Assembly of bio-nanochips)

The current project was devoted to the design, synthesis and investigation of chemical and physical properties of [2×2] grid-type complexes bearing biological residues (amino-acids, oligopeptides, nucleosides or long aliphatic chains).

The decorated [2x2] grid-type complexes formed starting from hydrazone-containing ligands combine the features of the two components: i) ligands bearing functional groups able to recognise other molecules by non-covalent interactions; and ii) the metal ions with their optical, magnetic and redox properties modulated by the environment (the primary and secondary coordination spheres).

The self-assembly of a specific multimetallic architecture from a set of organic ligands and metal ions, as a result of the processing of the structural information stored within the ligands by the metal ions operating through the coordination algorithm, may lead to materials with intriguing physical and chemical properties. In this respect, grid-like metalloarrays undergoing reversible switching processes of optical, magnetic and redox properties triggered by external stimuli (physical or chemical) are promising candidates for high-density information storage devices or sensing devices.
