Fig. 5

a Photographs of the p(phNA-co-BrNpA)-PMMA with light-printing QR code pattern in front of a photomask under 365 nm light. b Manufacturing process of the anti-counterfeiting patterns and the CPL spectrum of the patterns (top). The pattern of “8” was generated on each material using p(phNA)-PMMA first, and the hidden pattern was printed again using p(R/S-phNA7BrNpA3)-PMMA. Photographs of hidden pattern taken under UV irradiation (bottom). c Photographs of the fabrication and properties of the smart photoelectric material. When connected to the power supply, record the number corresponding to the lighted bulb as time progresses. First is the number 46, followed by 79, 1 and 258.
