Mounting spectroscopic and crystallographic evidence, however, shows that these bonds are dynamic, undergoing transient dissociation and reassociation without loss of framework integrity. This recognition has catalyzed the concept of dynamic coordination bonding, offering a fresh perspective on MOF chemistry and function. In this review, we define this concept and organize it into two complementary modes: (i) metal-guest dynamics at open metal sites and (ii) metal-linker dynamics within the lattice. We combine experimental and theoretical evidence demonstrating that bond dynamics underpin key functions-including non-thermal activation, gas adsorption, heterogeneous catalysis, and the formation of liquid and glassy MOFs. By integrating mechanistic insight with application-level performance, we establish dynamic bonding as a central design principle for MOFs and outline practical levers-metal identity, linker electronics and sterics, pore architecture, and crystal dimension-to tune equilibrium populations. Framed in this way, MOFs emerge not as static scaffolds but as responsive coordination networks, enabling next-generation advances in catalysis, gas storage and separations, and energy-relevant processes. 2026-02-28T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/59197 Title: FUNCTIONAL METAL-ORGANIC FRAMEWORK, METHOD FOR MANUFACTURING SAME, AND ATMOSPHERIC WATER HARVESTING APPARATUS USING SAME Author(s): 박선호; 허인철; 강민석; 유원철; 정낙천 Abstract: The method for manufacturing a functional metal-organic framework according to the present invention comprises the steps of: preparing a base metal-organic framework having a first porosity; and filling at least some of the pores of the base metal-organic framework by using a method in which the base metal-organic framework is provided with a functional oligomer, thereby manufacturing a functional metal-organic framework having a second porosity lower than the first porosity. https://scholar.dgist.ac.kr/handle/20.500.11750/59192 Title: POLYANILINE-CONTAINING METAL-ORGANIC FRAMEWORK FOR ATMOSPHERIC WATER HARVESTING USING OPEN COORDINATION SITES Author(s): 정낙천; 박선호; 유원철; 허인철 Abstract: The present invention provides a functional metal-organic framework (MOF) comprising a base metal-organic framework and a polymer formed within pores of the base metal-organic framework, wherein the base metal-organic framework comprises a metal having open coordination sites (OCS) and the polymer is formed by polymerization of an unsubstituted aniline; an aniline substituted with at least one substituent selected from the group consisting of halo, C1-C3 alkyl, C1-C3 haloalkyl, C1-C3 alkoxy, and hydroxy; or a combination thereof. https://scholar.dgist.ac.kr/handle/20.500.11750/58984 Title: Coordination Exchanges in Metal-Organic Frameworks Author(s): Jeong, Nak Cheon 2017-08-22T15:00:00Z
