The reliance on fossil fuel resources, dating back to the Industrial Revolution, has led to drastically increasing energy demands, and a resulting increase in anthropogenic greenhouse gas emissions, particularly carbon dioxide (CO2), in the atmosphere. These rising CO2 levels are recognized as a global problem that requires new approaches, including novel functional materials, to solve this challenge.1 To contribute solutions to address these challenges, we have focused our efforts in recent years on the production of functional polymeric materials.2 The focus in this presentation will be on the various strategies we are employing to tune properties, structure and functionality in conjugated microporous polymeric (CMP) materials.3 We have developed a method, the so-called Bristol-Xi’an Jiatong (BXJ), to tuneably address surface areas, pore sizes and pore size distributions, and functionality in conjugated microporous polymers.4 This approach explores matching the Hansen Solubility Parameters (HSPs) of the growing polymer chains with the solvent – better matching leads to higher solubility, and better control over the mentioned properties. The versatility of these materials is shown in their wide application areas: a) in energy storage devices,5a b) for the removal of harmful pollutants from water,5b,c and c) metal-free and co-catalyst free conversion of CO2 to fuels,6a and other valuable chemical feedstocks.6b Further areas that are currently being explored relate to the use of our porous materials for H2 storage. These porous framework materials present an exciting platform to address the global challenges we currently face in a green and sustainable fashion.
