Aggregation-Induced Emission, 2 Volume Set

Professor Ben Zhong Tang, The Hong Kong University of Science & Technology, Hong KongBen Zhong Tang, is a Chair Professor in the Department of Chemistry at The Hong Kong University of Science & Technology. He is interested in the creation of new molecules with novel structures and unique properties. The Aggregation-Induced Emission (AIE) phenomenon was first discovered by Professor Tang and the first paper about AIE was published by Tang and coworkers in 2001; this paper has already been cited over 600 times. Professor Tang has acted as a guest editor for Macromolecular Chemistry and Physics, organizing three special Series on Functional Polymers. He also organized a special issue in the Journal of Inorganic and Organometallic Polymers and Materials to honor of Professor Ian Manners in 2007. He is currently serving as Editor-in-Chief of the Polymer Chemistry Series and Editor of Polymer Bulletin. Professor Anjun Qin, Department of Polymer Science & Engineering, Zhejiang University, ChinaAnjun Qin is an Associate Professor in the Department of Polymer Science and Technology at Zhejiang University, China. One of his research interests is to design and synthesize polymers with AIE characteristics and to explore their applications in chemosensors and bioprobes.Between them, the editors have published more than 400 peer-reviewed papers and 40 book chapters.
