Molecular Engineering of Functional Porous Organic Polymers for CO2 Capture and Conversion<\/p>\n
The increasing concentration of CO2 emissions in the atmosphere remains a primary driver of global climate change, making the development of advanced CO2 capture and utilization technologies an industrial and environmental imperative. This seminar outlines a systematic journey in the molecular engineering of porous organic polymers, demonstrating the strategic use of the synthetic chemistry toolbox to transform discrete molecules into sophisticated porous architectures for effective carbon management.<\/p>\n
The talk begins with the transition from molecular cages to extended porous networks, emphasizing the precise control over porosity and CO2 adsorption performance.1 We will then focus on the simultaneous capture and chemical fixation of CO2 into value-added cyclic carbonates, facilitated by charged polymeric frameworks, known as \u201corganic zeolites\u201d.2 The discussion extends to direct air capture and subsequent conversion via sterically confined N-heterocyclic carbenes. Furthermore, the development of new sustainable synthetic routes using elemental sulfur will be presented as a strategy to improve cost efficiency for large-scale environmental applications. The talk then evolves into our landmark development of \u201cCovalent Tricycloquinazoline Networks (CQNs)\u201d, introducing a new chemical space through ionothermal synthesis.3 Building on this, I will present our recent work on monomer-engineered CQN extensions that demonstrate exceptional performance in CO2 mitigation and iodine capture. The talk concludes by illustrating how subtle structural modifications at the molecular level enable precise control over the CO2 capture capacity of the materials, bridging the gap between fundamental molecular design and practical environmental solutions.<\/p>\n
