Our core technology, porous coordination polymers (PCPs; also known as metal-organic frameworks (MOFs)), is based on research developed by Distinguished Professor Susumu Kitagawa at the Institute for Advanced Study at Kyoto University. Atomis aims not only to provide solutions such as the optimization for manufacturing processes of PCPs, but to also develop applications that provide innovative value using these materials.


Features of porous coordination polymers (1) – Design

A porous coordination polymer (PCP) is also called an organometallic structure (MOF), in which the metal and the organic compound have regularity and continuously form a three-dimensional structure, and the porosity controlled at the nano level is achieved. It is a substance that has. It has the feature that the pore space can be freely designed (designability) by selecting metal and organic ligands.

Features of Porous Coordination Polymer (2) – Flexibility

Unlike conventional porous materials (activated carbon, zeolite, etc.), the porous coordination polymer is constructed with a flexible bonding mode (coordination bond), and it may have a structure with openable and closable pores. It is possible and exhibits a sigmoid type adsorption/desorption performance such that the switch is turned on-off.

Features of porous coordination polymers (3) – multifunctional

Using aligned pores of porous coordination polymer, research on new functions such as ion transport, electron conduction, electromagnetic properties, and photoexcitation as well as molecular adsorption, separation, transport, alignment, synthesis, and catalysis can be conducted. It is being advanced. It is being considered not only in the energy and environmental solutions industry but also in a wide range of industries such as food, pharmaceuticals, electronic components, electrical equipment, building materials, chemistry, semiconductors, and space development, and is expected to have a major impact on the industrial field.
