Metallopolyynes and Metallophosphors: New Multifunctional Materials
with Emerging Applications
(Department of Chemistry, Hong Kong Baptist University) WONG, Wai-Yeung
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
metallopolyynes and metallophosphors which can exhibit easily tunable luminescent and
electronic properties. Considerable focus is placed on the evaluation of their suitability as
emitters in OLEDs for display and lighting applications, optical power limiters for sensor
protection, semiconductors in organic photovoltaic cells for solar power generation and
polymer precursors to metal alloy nanoparticles for magnetic data storage application. The
approaches based on structural modification of the organic chromophore to achieve multiplecolor phosphorescence emission and to tune the optical and photovoltaic properties of these
organometallic materials will be presented.
