On March 27, 2023, the Photonic Nose and Molecular Materials Group held a postdoctoral report defense session for Dr. Liu Ke in Room 1668, Zhizhi Building, Chang’an Campus, at which Dr. Liu Ke presented his research report titled “Intramolecular hydrogen bond regulation of fluorescence behavior of carborane derivatives and its sensing applications”.

Liu Ke’s postdoctoral work mainly focuses on the regulation of intramolecular hydrogen bonds and sensing applications of carborane biofluorescence behavior. He introduced intramolecular hydrogen bonds into the o-carborane small molecule system, thereby regulating the photophysical behavior of o-carborane derivatives and constructing a novel o-carborane fluorescent sensing molecular system. In addition, he introduced intramolecular trans-space charge action, realized the precise manipulation of intramolecular proton transfer process, and developed related solid-luminescent materials, obtaining an important breakthrough in the fluorescence behavior regulation strategy of o-carborane derivatives, and laying a foundation for related applications. During this period, Liu Ke published 5 academic papers in high-level journals including JACS as the first author or corresponding author, and was funded by the National Natural Science Foundation of China Youth Fund Project, the China Postdoctoral General Program, and the Special Project for Basic Scientific Research Business of Central Universities.

Prof. Liu Feng of Xi’an Jiaotong University served as the chairman of the defense committee, Prof. Tian Wei of Northwestern Polytechnical University, Prof. He Gang of Xi’an Jiaotong University, Prof. Ding Liping and Prof. Liu Jing of Shaanxi Normal University served as members, and Associate Professor Liu Xiaoyan of Shaanxi Normal University served as the secretary. The Defence Committee unanimously agreed that Dr. Liu Ke’s research achievements were remarkable, his academic insights were unique and innovative, and he had the ability to carry out research work independently.
