Functional organic materials are prevalent in many fields, including electronics,¹  porous materials,²  polymers,^3,4  and ionic liquids.⁵  We define the scope of organic materials here as materials formed from small or polymeric molecules constituted of only light elements. We do not include pharmaceutical drugs and biological materials as these are covered elsewhere, although we will note similarities in the problems faced and the approaches that can be used to tackle them. The discovery of new materials has previously been dominated by serendipity, but there is now a clear need to accelerate their discovery to help tackle the...
