In the version of the Feature 'Organics go hybrid' originally published (Nat. Photon. 11, 20–22; 2017), in the following sentence 'carbohydrate chain' should have been 'conjugated hydrocarbon chain', thus it should have read “The excitement all started with polyacetylene (CH)x′ the simplest conjugated hydrocarbon chain in trans and cis isomers.” Corrected in the online versions 6 January 2017.
