| Research Abstract |
In this project, we first established strategies for assembling and organizing molecules on the basis of two guiding principles that, when properly designed, molecules can attract or repel each other selectively, and that dimensionality of the structures is most instrumental in controlling the properties and functions of molecular assemblies. We then designed molecules that have the functional groups for exhibiting weak intermolecular interactions such as coordination bonds, hydrogen bonds, hydrophobic interactions, dispersion force, exchange interaction, etc. The varieties, numbers, locations and vectors of such groups will tailor the size and shape of the resulting molecular assemblies. After the synthesis of the designed component molecules, the assemblage and organization of them have been performed by : 1. Self-assembly, 2. crystallographic technology, 3. monolayer/bilayer methods, 4. molecular manipulation by scanning probe microscopy. These methods will be applied not only for s

ingle components but also for two or more components.
Since mechanical, optical, electronic, magnetic and chemical interactions are expected to be directional and anisotropic in these organized molecular assemblies of mesoscopic scale, the following molecular functions and functional molecular materials which have never been attained by assemblies of naive molecules will be produced. One-dimensional materials : Double-helix information storage mimicking DNA, molecular sensing, highly ordered metal-ion array catalysts, Two-dimensional materials : Creation of morphologies found in living organism, interfaces enabling chiral recognition, two-dimensional metal complexes Three-dimensional materials : Two-dimensional reaction environments by multiplication of artificial molecular bilayers, organic zeolites, molecular optomagnetic recording devices, transparent magnets.
We believe that research achievements obtained through this Project will become a milestone linking the 20th century to the 21st century and open a door toward the new era of science. Less
