Metallophosphors and metallopolyynes of the transition metal elements have recently received considerable attention as molecular functional materials in various areas, such as organic light-emitting diodes, photovoltaic devices, oxygen sensors, optical limiters and two-photon absorption materials, etc. Their photophysics, charge transport and energy transfer mechanism are greatly influenced by the chemical environment around the transition metal center which consequently affects their performances in these applications. Therefore, much current focus has been put on studying the structure-property relationships of functional metallophosphors and metallopolyynes. A deep understanding of these correlations can provide important information in designing molecules which are suitable for a particular optoelectronic application with enhanced performance.
