| Abstract: | Solvatochromic materials have recently attracted increasing attention owing to their great significance in the security and sensor fields. In this study, ultrafast explicit and implicit information was collected regarding a fluorescent nanocellulose membrane produced from nanocellulose membranes coated with a Zn-terpyridine complex (Zn-tpy) in a layer-by-layer manner. The fluorescent emissions of the nanocellulose membrane changed from yellow (CIE: x=0.37, y=0.45) to green (CIE: x=0.32, y=0.47) under a dichloromethane environment and 365-nm irradiation. Due to the ease of dichloromethane volatilization, fluorescent emissions quickly returned to the original state. These solvatochromic nanocellulose membranes, with ultrafast explicit and implicit information, exhibited valuable application prospects in anti-counterfeiting techniques. |
