Crystal Structure of Coordination Polymer

Design Principles

We strategically design and synthesize novel hydrogen-bonded coordination polymers (HBCPs) by tuning metal centers, ligands, and functional groups.

금속 중심체, 리간드, 기능기를 정밀하게 조절하여 새로운 수소결합 배위 고분자(HBCPs)를 전략적으로 설계하고 합성합니다.

Characterizations

We investigate the mixed transport of protons and electrons to elucidate the fundamental mechanisms of proton-electron coupling within HBCPs.

HBCPs 내에서 양성자·전자가 동시에 흐르는 현상을 규명하고, 양성자-전자 결합의 근본적인 원리를 이해합니다.

Applications

We explore advanced applications of these materials in next-generation functional platforms, such as neuromorphic systems and adaptive sensing devices.

개발된 소재를 인공지능 반도체 및 적응형 센싱 소자 등 차세대 고기능성 플랫폼 에 응용합니다.
