German Applied Chemistry published by Professor Xie Xiaolin, Huazhong University of science and technology

Recently, German Journal of Applied Chemistry published the latest research results of Professor Xie Xiaolin, School of chemistry and chemical engineering, Huazhong University of science and technology: "crosstalk free pattern of cooperative thermosensitivity images by the synergy of the aiegen based on the synergistic effect of aggregation induced luminescence and liquid crystal with the LiquidCrystal Angew Chem Int Ed DOI: 10.1002/anie.201915053 ）”。 Huazhong University of science and technology is the first completion unit The first author is Zhao Ye, Ph.D student of School of chemistry and chemical engineering, Associate Professor Peng Haiyan as the corresponding author, Professor Xie Xiaolin, Professor Li Zhong'an, Ph.D student Zhao Xiaoyu and Professor Li Mingde of Shantou University as co authors Laser holographic anti-counterfeiting technology is widely used in famous products, banknotes, passports and other fields Holographic polymer materials based on holographic photopolymerization induced phase separation promote the development of this technology On this basis, multi image storage and its dynamic response function are of great significance to improve the capacity of anti-counterfeiting identification information and enhance the security of anti-counterfeiting, and the non crosstalk storage of multi image is a problem to be solved urgently The research team has been committed to the research of holographic polymer composite materials, and has made a series of important research progress in the past few years: proposed "photoinitiator" The concept of holographic polymer composite material can effectively control the rate of photopolymerization and promote the phase separation The mathematical model of holographic polymer composite material processing is established to provide theoretical guidance for the optimization of holographic processing technology A variety of color holographic image storage technologies such as master hologram, physical hologram and digital hologram are innovated On the basis of the above work, through continuous innovation, the team introduced the aggregation induced luminescence into the holographic polymer composite materials, and successfully realized the crosstalk free integrated storage and collaborative temperature response of the holographic image and the fluorescent image by using its synergistic effect with the liquid crystal, which is expected to be applied in the high-end anti-counterfeiting field This work was supported by the key project of NSFC (51433002), general project (51773073), the peak climbing plan of Huazhong University of science and technology and the special fund of basic scientific research business cost of Central University (2019kfyrcpy089).
