Infinite Coordination Polymer Particles from Polymeric Coordinating Precursors
Abstract
Infinite coordination polymers (ICPs) represent a highly tailorable class of inorganic materials that can be reversibly assembled and disassembled in response to specific chemical or physical stimuli. ICP particles are typically synthesized via a modular approach, for which multidentate organic ligands are linked through cationic metal nodes to form extended polymeric structures. The highly modular synthesis and stimuli-responsive nature of ICPs enable their chemical composition and physical morphology to be tailored for a wide range of applications including those of interest to the ARO, such as small molecule detection, catalysis, drug delivery, gas storage, and chemical separations. Many such applications depend on the ability to predictably tune the size and shape of ICP particles and, as a result, control their physical properties such as surface area and porosity. The major goals of this project were to develop new approaches for the controlled synthesis of ICPs. In particular, we aimed to access ICP particles further along the particle condensation pathway via the assembly of soluble and stimuli-responsive polymer precursors. Broadly, the work discussed herein allowed us to explore and develop novel polymers that undergo predictable conformational and/or chemical changes in response to specific external stimuli, while targeting applications in nanoparticle technology.
