A series of D-π-A, D-π-D, and A-π-A based push-pull compounds with triarylamine and benzophenone were designed and synthesized for nonvolatile memory applications. All of the compounds showed good solubility in common organic solvents, which permits solution processability. D-π-A based compounds exhibited write-once-read-many (WORM) memory applications, and the compound with a methoxyphenyl substituent exhibited switching with a low threshold voltage of -0.82 V, an ON/OFF current ratio of 102, and a long-lasting retention time of 103 s. The effect of differently functionalized triarylamines on memory behavior was explored by optical, electrochem., and computational studies. The highest HOMO levels of around 5̃.0 eV and irreversible anodic peaks (0.7-1.3 V) obtained for the compounds facilitate charge injection and switching behavior. Besides, electrochem. and d. functional theory studies disclose the charge-transfer mechanism of the D-π-A systems, which is related to the bistability of the devices. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Recommanded Product: 128-08-5).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
