BIO:

Wai-Yeung Wong (Raymond) received BSc (1992) and PhD (1995) degrees from the University of Hong Kong. After a postdoctoral year with Prof. F. Albert Cotton at Texas A&M University in 1996, he worked for Profs. The Lord Jack Lewis (FRS) and Paul R. Raithby at the University of Cambridge in 1997. He joined Hong Kong Baptist University (HKBU) as an Assistant Professor in 1998, rising through the academic ranks to Chair Professor in Chemistry in 2011. He served as the Head of the Chemistry Department at HKBU from 2014 to 2016. Recently, he has moved to work at the Hong Kong Polytechnic University and is currently the Associate Dean of the Faculty of Applied Science and Textiles and Chair Professor of Chemical Technology. His research interests lie in the areas of molecular functional materials (especially for metallo-organic molecules and metallopolymers) with energy functions and photofunctional properties as well as nanomaterials and their technologies. Professor Wong is currently the Regional Editor of Journal of Organometallic Chemistry, Associate Editor of Journal of Materials Chemistry C and Editor of Topics in Current Chemistry, and serves on the editorial/international advisory boards of Scientific Reports, Advanced Optical Materials, Chemical Record, Chemistry: An Asian Journal, Dalton Transactions, Dyes and Pigments, Macromolecular Rapid Communications, Macromolecular Chemistry & Physics, etc. At present, he is the President of the Hong Kong Chemical Society.

 

ABSTRACT:

"Multifunctional Polymetallaynes: Properties, Functions and Applications"

 

Inclusion of transition metal elements into organic scaffolds allows the hybridization of the interesting physical characteristics of metal complexes such as electronic, optical and magnetic properties with the solubility and processability inherent to the organic-based molecules. This lecture highlights the recent development of some multifunctional rigid-rod polymetallaynes (especially those with platinum center) which can exhibit easily tunable optical, electronic and magnetic properties. Considerable focus is placed on the evaluation of their suitability as emitters in PLEDs, optical power limiters for eye and sensor protection, semiconductors in organic photovoltaic cells for solar power generation, cathode materials for energy storage in organic batteries and solution-processible polymer precursors to metal alloy nanoparticles for magnetic data storage application, etc. (Figure 1). The approaches based on structural modification of the organic chromophore to achieve tunable absorption and emission properties and to tune the optoelectronic and magnetic properties of these organometallic polymeric materials will be presented.
