Porous polymers for energy conversion and storage Sebastien Rochat a,b,c , Stella Wang a , Honor Westlake a , James Davies a , Josh Pepper a a School of Chemistry, University of Bristol, Bristol, UK, b Bristol Composites Institute, Faculty of Engineering, University of Bristol, Bristol, UK, c Department of Engineering Mathematics, School of Computer Science, Electrical and Electronic Engineering, and Engineering Maths, University of Bristol, Bristol, UK Conjugated and microporous olymers are materials which possess a unique combination of properties, the most important being a permanent, accessible microporous structure, and a p-conjugated system. Owing to their convenient synthetic modularity, strategies to tune their structure and properties on demand have been established, resulting in varied applications such as gas storage and separation, water treatment, (bio)chemical sensing, catalysis, organic electronics and energy storage devices. [1] In this presentation, I will show how the optical and electronic properties of materials referred to as Polymers of Intrinsic Microporosity (PIMs) [2] can be adapted to efficiently perform tasks related to energy conversion and storage. I will present how the electronic properties of this class of polymers can be modelled computationally using density functional theory (DFT) to pre-select materials prior to their synthesis and characterisation. Then, energy- and environment-relevant applications will be presented where the polymers are used to perform electrocatalysis (focusing CO 2 reduction reactions), and where they are employed as spectral converter in luminescent solar concentrator devices (LSCs).
