Publisher Correction: Bistable and photoswitchable states of matter

The original version of this Article contained errors in Fig. 3. In Fig. 3a, the word ‘fluid’ in grey was incorrectly given as ‘solid’ in green, below that, ‘solid’ in green was previously ‘fluid’ in grey. Also, the label on the arrow incorrectly read ‘TMG (1 mol%) HABI-Cl (3 mol%) 455 nm, 1 min’; the correct version reads ‘TMG (1 mol%) HABI-O- n -oct (4 mol%) 455 nm, 4 min’. In the accompanying legend, the word ‘photobase’ was originally incorrectly given as ‘photoacid’. Additionally, in Fig. 3b, the label on the central image was ‘As is: solid’, rather than the correct ‘As is: fluid’. This has been corrected in both the PDF and HTML versions of the Article.
