Light responsive Organometallic Thermoelectric and Magnetoresistive systems
Keywords : Metal-acetylides, π-conjugated systems, photochromism, optoelectronic memory devices
Organic Magnetoresistive (OMAR) and Thermoelectric (TE) materials hold great promises for the development of smart electronic devices and for environmental issues. Both phenomena stem from the peculiar behavior of charge transport from one electrode to the other when submitted to external magnetic fields (OMAR) or heat flow (TE). However, today’s higher OMAR and TE performances are not satisfying. Therefore, new molecular systems featuring improved OMAR and TE properties must be developed. In addition, controlling the transport with an external stimulus is a key step to obtain smart TE and OMAR materials, paving the way for the design of molecular memory devices and coolers. Our efforts are currently directed at designing appropriate photochromic & organometallic metal-bis acetylides systems towards TE and OMAR technologies. These unique photoswitchable systems will be implemented and evaluated in devices as self-assemblies (transistors) or in molecular junctions.
