The Park Lab is actively developing functional organic-inorganic hybrid materials for their environment, energy, and biotechnology-related applications.The research is interdisciplinary over organic chemistry, inorganic chemistry, and analytical chemistry.

1. Metal-Organic FrameworksMetal-organic frameworks (MOFs) as a class of well-ordered porous crystalline materials have attracted continuous interests owing to their structural and functional diversity as well as high porosity and large surface area. The structure, pore size, and surface functionalities of MOFs can be designed and finely tuned by judicious choices of building blocks such as metal-containing nodes and organic linkers. Introduction of functionalized pores into MOFs can lead to their diverse applications, such as gas storage, separation, catalysis, and drug delivery.
– Stimuli-responsive MOFs for environmental applications– Porous photocatalysts for CO2 utilization– Sensitive and selective adsorbents for environmental applications
2. Metal-Organic Polygons/PolyhedraAmong such self-assembled structures, diverse metal-organic polygons/polyhedra (MOPs) have been designed and prepared based on inspirations drawn from geometric entities such as Archimedean/Platonic solids and biological units with multiple interaction sites.
We are especially interested in stimuli-responsive MOPs due to their potential applications in diverse fields including drug delivery, adaptable surface coating and controllable molecular machines. The designability and intrinsic porosity of metal-organic polyhedra/polygons (MOPs) present an opportunity for developing new types of stimuli-responsive materials.
– Visible light-responsive MOPs for drug-delivery applications– MOPs as a building block of MOFs
3. Porous Polymer Networks (PPNs)Porous polymer networks (PPNs) which are consisted by strong covalent bonds has large porosity and stability. We design the structure of PPNs, modify their properties to apply electric device and others.
– Product-selective porous catalysts– Metal-free porous photo catalysts– Porous polymers as battery electrode materials
4. Organic-Inorganic Nanohybrids
