We report on the growth and characterization of crystalline 1,1-dicyano-2,2-(4-dimethylaminophenyl)ethylene (DDME) thin film with electrical switching property. X-ray diffraction analysis indicates that bulk single-crystal DDME belongs to monoclinic, space group P21, Z = 2 structure. Optical spectroscopy shows chemical structure is consistent powder material, suggesting material very stable during vacuum thermal deposition process. Scanning probe microscopy transmission electron observations...

A thin film of 1,1-dicyano-2,2-(4-dimethylaminophenyl) ethylene (DDME) has been grown by a modified vacuum deposition. The films were characterized Fourier transform infrared spectroscopy, transmission electron microscopy, and scanning tunneling microscopy (STM). Highly ordered parallel molecular stacks repeatedly observed with STM under ambient conditions. dc current–voltage (I–V) characteristics device Au/DDME/Au measured, the was found to possess good electrical bistability electrochromic...
