Resource:   National Natural Science Foundation of China(Key Program)
Abstract:   By means of organic ligand design and oriented preparation of organometallic compounds, our research is focused on systematic studies of the syntheses, characterization, and properties of organometallic optoelectronic materials with on-off effects. Taking advantage of on-off effects from organic ligands to regulate the rate and efficiency of intercomponent electron and energy transfers, the desired luminescence and optoelectronic properties can be achieved. The influence on metal-metal electron transfer and organometallic molecular conductance from on-off effects will be investigated to reveal the correlations between structures and properties. By regulating the degree of energy transfer between organometallic chromophores, dual luminescence

Designed syntheses of organometallic functional materials that exhibit optoelectronic on-off behavior will be carried out to achieve luminescence vapochromism, tribochromism, and mechanochromism etc. Modulation and optimization of the optoelectronic properties can be attained by variations in organo-functional group or substituents as well as modification of the structural sensitive sites in organometallic chromophores. The general patterns will be explored concerning syntheses, structures, spectroscopy, and property modulation in optoelectronic functional materials with on-off effects. It is expected to make a breakthrough in exploration of optoelectronic materials and devices with potential applications.
