a) Construction strategies of ac‐CDots via self‐assembly strategies. b) i) SEM images of cholesteric ac‐CDots film with helical pitch 740 nm. The inset images in (i) were the photos of the ac‐CDots film illumination under LCP and RCP, respectively. ii) g_lum value of c‐CDots films with different helical pitch (Blue: 420 nm; Green: 600 nm and red: 740 nm). iii) Photography of ac‐CDots film illumination under natural light, LCP, and RCP, respectively (from left to right in the upper panel); The ac‐CDots films were excited by with the 254 nm lasers, photoluminescence images of the films were recorded during turning off the lasers 2 s from left to right ((ii) in the bottom panel). (iv) The proposed CPRTP mechanism for the ac‐CDots film.^{[ 38 ]} Reproduced with permission from ref. [38].
