"Molecular technology" is a new concept of academic research aiming to transform conventional science and technology by designing and synthesizing materials with desired physical, chemical, and biological functions at the molecular level. To create desired properties at the molecular level, one idea is to select the most suitable candidate molecules from an infinite number of molecules with the aid of theoretical and computational science. Further, atomic-level characterization of materials also supports the progress of molecular technology. We aim to build technologies that lead to the creation of innovative and precise new substances, materials, devices, and processes that cannot be considered as an extension of conventional molecular libraries and chemical technologies. Molecular technology will lead to overcoming interdisciplinary problems that were difficult to solve with the traditional academic fields such as chemistry, physics, and biology. This symposium is expected to attract diverse participants, including academia, government, and industry.
