Organic memory devices based on a bis-cyclometalated alkynylgold(III) complex.

A bis-cyclometalated alkynylgold(III) complex, [Au((t)BuC^N^C(t)Bu)(C≡C-C6H4N(C6H5)2-p)] ((t)BuHC^N^CH(t)Bu = 2,6-bis(4-tert-butylphenyl)pyridine), has been synthesized and characterized. The complex was found to exhibit rich photophysical and electrochemical properties. More interestingly, the complex has been employed in the fabrication of organic memory devices. The as-fabricated memory devices exhibited good performances with low operating voltage, high ON/OFF ratio, long retention time, and good stability.
